Firefox won't start anymore

For some time now, I can't even start Firefox (even the latest version 146) on Windows 10. Firefox appears briefly in Task Manager, and then disappears. Refreshing and/or reinstalling doesn't work either. Only when I install Firefox in Windows 10's safe mode can I start it again. Then, in normal Windows mode, it works once, but then fails again. I don't get an error message. Holding down Shift doesn't work either. Chrome works, and so do all other programs. On another PC with Windows 11, with the exact same settings, there's no problem at all. Is anyone familiar with this problem?

No, I tried all these possible solutions before I posted my question. These did not help to solve my problem.
