Error Firefox

Hello,

I am looking for help with a Windows 11 Pro 24H2 system. Firefox no longer works despite a clean uninstall and reinstall, including deleting all related folders.

When I reinstall Firefox, the error appears, but the application still manages to launch. However, after a system restart, the issue comes back.

When launching Firefox, I get the following message: “Firefox.exe failed to start correctly (error 0xC0000022).”

I can’t find any recent information about this issue. Thank you in advance for your help.

Do you possibly have SentinelOne software?

It should be fixed in 146.0.2. You can try to turn off the Sentinel client for confirmation.

See bug 2005255.
