Steam won't open on Windows 11

[BuG]

As per title. Ever since a combination of either Windows update or Steam, I cannot open Steam at all.

I can see the process in the task manager but no windows nothing. No error messages. I uninstalled/reinstalled a dozen times, tried everything I could find on the troubleshooting guides etc but no luck. Support could not help.

Wondering if anyone has any magic idea or if there is a way to enable some "forced" logging so that I could maybe get an idea what is going on and why it won't open?

Any help is appreciated (I just do not want to reinstall my machine just for that... :()

Thanks!

Checking some of the log files. I'm seeing this in one of them:

Any idea what that means?

And this one in another:

I'm sure you can read same log, ask Nvidia support live chat, but please reinstall gpu driver in custom and make clean install then option is there can be a good idea before talk with nvidia.

[BuG]

Appreciate the suggestion but I have already used DDU several times to re-install the drivers and no differences. I do not think it is a graphic drivers issues at this point

I'm also seeing this error in another log file:

not sure what they mean..

[Iceira]

Most crash log will not mention this at all if its not effect by it
"The GPU process has crashed 2 time(s)" ( from OC to things cause and effect ) this is why i and bet other will say same thingy its not a app crash its a GPU crash. hope you can understand why i and maybe other think this.

[BuG]

Yep totally understand. I did another round of DDU and gpu crash lines in the logs are all gone now after another re-install of steam. Its still not working.

the cef log file is showing only this:

There are a number of people with the same issue - started on the weekend. Steam support not got an answer yet. If enough of us keep on at them, then maybe they might up the priority. I have spent over 12 hours, so far, trying to come up with a solution - and nothing.

I’ve indeed seen reports all over the internet since back to February with this issue. Many had it fixed with unplugging razer stuff, runing admin etc etc. I’ve tried everything I could but no differences so far.

Steam « support » was or no use. Sorry but i’m not even sure why they have a support where all they told me was a link to the general troubleshooting page and « go search on the internet »

Been 3 weeks now for me being unable to use steam, getting very frustrated with this when everything else works perfectly fine on my machine.

I tried some workaround last night to start steam from an older build via the internet archive and then prevent the update plus run in -vgui mode. That works fine but can’t update games etc in this mode sadly….

Does the error occur before using the latest gpu version?????

[BuG]

Yep tried rolling back just to test but same issue.

hello
Try to use the less software in auto run on startup , just to be sur there is nothing that can be interfering with steam

[charana100]

Having the exact same issue as of now. Steam crashed, did an update and now it does not start anymore. I tried the same proposed fixes - none of them heped.

[BuG]

Starting Windows (from msconfig) with stuff disabled makes no difference. If only we could enable some sort of verbose logging to have a clue what is upsetting this damn client...

[PikaMug]

Same here. Worked fine until updating to client version 1718305227. Tried reinstalling Steam, sfc /scannow, various shortcut args, antivirus exclusion, reinstall gfx drivers... nothing helped. Windows 10 with AMD card.

Edit - This appears to be the main thread for the issue: https://steamcommunity.com/discussions/forum/1/6725643788916599657/
