Steam Won't Open, Closes INSTANTLY

[Nikeisfake0]

When I open my steam, it doesn't appear. I have checked taskmanager: when i open steam, one steam process starts, then terminates immediately.

What i have tried (without success):
1. Removing the steam cache
2. Reinstalling steam
3. Checking for any malware in the steam folder
4. Launching a game (steam games won't start because steam won't, probably to prevent piracy)
5. Starting steam.exe directly (Without the shortcut)
6. Restarting my PC and running steam.

Try windows safe boot mode, ( google how to do )

and check windows event viewer if you are lucky the windows log has maybe a crash issue why app crashed.

[Iceira]

you can google this "steam ntdll.dll"


make sure you are not in steam beta , unless you need to be there, BETA can also cause more issue, many steam user forget they are in steam beta until it give issue.

i did not say you are, but more get out off it while you test for this.

Try running steam as admin

[Satoru]

Your OS is in bad shape

1) run a full windows update and reboot

2) temporarily disable your anti virus and see if that help

3) run steam as an administrator

[Phénomènes Mystiques]

There was a problem in May 2024 and here is that solution which may work (it deals with this same issue plus Steam boot loop and high RAM usage):

Go to your Steam installation drive folder:

Steam\userdata\(account number)\config\librarycache


Delete:

achievement_progress.json


Restart Steam Client.


The file will be recreated upon next client launch and is a redundant .json file.

This solution also fixes Steam Client and Webhelpers high RAM usage issue/bug.

You run Steam at PC Startup (the default setting), go to Task Manager < Startup and make sure the Steam Valve logo is attached to the application, if it appears blank, you have registry corruptions which this feature can cause (it did it to me as well and other applications such as MS Teams can also have this issue as I have seen in the past) - for this fix, simply follow this article below then reinstall the removed application but do NOT allow the application to automatically start at PC startup because some do not play nice and if you wanted the application(s) to run at PC startup properly, it is safer to make a task for it in Task Scheduler:
