steamwebhelper, a critical Steam component, is not responding. The Steam UI will not be usable.

I've had this error pop up 2 days ago and I haven't been able to fix it. I'm running Windows 11 and after one of the latest updates I haven't been able to run steam. I've tried everything I've read, here's a list of what I've tried (some of which I can remember as of now):
- Uninstall the last windows update
- Delete steamwebhelper from C:\Program Files (x86)\Steam\bin\cef\cef.win7 and cef.win7x
- Run compatibility mode for Windws 8, disable fullscreen optimizations and running the program as an administrator
- Deleted my achievments folder
- Deleted usardata folder, and config folder inside of it
- Add it to my antivirus program whitelist, turned off antivirus, turned off firewall
- Disabled GPU acceleration
- Deleted Steam completely from the Program Files (x86) folder AND from the Users folder, and reinstall it from a fresh setup.exe
- Deleted Steam completely and reinstall it in Program Files instead of Program Files (x86)

At this point I don't know what else can I do, I have gone through tons of videos, reddit posts, Steam forum threads, etc., and I still can't open it, if anybody knows something I haven't tried or has had the same problem as me and solved it I'd be so happy to hear you.

Thank you so much! I was tinkering with TCP in order to fix long connection times. Haven't rebooted my laptop after that for some time, so would've never guessed that was the issue. Your post saved me a lot of time!

Glad my post helped you, I still have 0 clue what TCP is but I'm glad I found a solution and was able to help others.

This happened to me after updating ASUS Armory Crate that's linked to my motherboard.
After uninstalling Armory Crate it fixed my steamwebhelper, a critical Steam component, is not responding problem

I have this now.. and nothing helps :(
Gives me some error "get player" or something.. I think I do have to try that TCP :/

Idk man, I really have no idea but give that TCP thing a go, maybe it works, it has worked for so many people now

I have been having this problem for a month or so. WIN11. Steam used to run no problems and now I can barely launch it. tried to tick all the different restart options, uninstall everything and reinstall (while also removing all Steam folders from the PC).
No matter what i do it keeps saying the same thing..

The TCP thing seems to be Linux related (i am no IT wizard) and I am failing at disabling it on Windows.

Do you have any other idea or thread for me to look at? Desperation :(

Hey whats up man, I haven't seen any other posts or anything else talking about this problem other than the one I saw from this random guy that said that TCP BBR2 was causing this issue.
I'm even less of an IT guy myself so what I did was just ask copilot (window's AI assistant), or you can ask chat GPT I guess, just ask how can you turn off or disable TCP BBR2 step by step, just follow whatever the AI tells you and it should work, that's what I did in my case. Hope it helps.

Appreciate the heads up but even GPT agrees:

Windows 11 does not support TCP BBR2 (Bottleneck Bandwidth and RTT), as it is a congestion control algorithm primarily used in Linux-based systems. Windows uses other congestion control algorithms like CUBIC and New Reno.

How can I be paying for games and not be able to run them is.. infuriating :(

"To disable TCP BBR2 on Windows 11, you can use the command in the Command Prompt or PowerShell. Here's how:
1. Open Command Prompt or PowerShell as an administrator.
2. Run the following command to set the congestion provider to "none" or another desired algorithm: netsh int tcp set supplemental Template=Internet CongestionProvider=none
3. You can verify the change by running: Get-NetTCPSetting | Select SettingName, CongestionProvider

This will disable TCP BBR2 and revert to the default congestion control algorithm. Let me know if you need further assistance!"
Hope it helps!

And what would you write to change it back in the future?
Thanks :)

I managed to disable it and now it runs normally... wow. To start: thank you Hig!!

One thing, but i only tried it yesteday: I had network issues more than usual with Helldivers 2. This could have just been a bad day for servers though, would not be the first time.

Is there any chance that disabling TCP BBR2 impact my network performance in game? I am not IT intelligent enough to actually know it.. chatgpt say it might but no idea in this specific case.

[Dr.Shadowds 🐉]

Asking what BBR2 stand for it Bottleneck Bandwidth and Round-trip time.

If have to disable it, means either there issue between you to the server, the issue on your end, or app itself the problem. By disabling this you default to another TCP algorithm like Cubic. There can be issue with BBR2 compare to BBR this can affect things.

[JTVallo]

I take it back. I am now having the same problem again.. this is mental. Updated all possible drivers trying to fix it and nothing. So frustrating to not being able to play anything on Steam for whatever unknown reason.

Seriously, it's just unfair that we have to troubleshoot stuff like this when it should sit with the provider to make sure things work.

If anyone else have any idea it would be greatly appreciated :(
