Windows 8.1 build 9600
I will repeat once again everything worked before the Steam update

I do not want to reinstall Windows

If you're in Steam beta opt out. Or redownlisd Steam files, to do this, go to where you install Steam, delete everything except for Steamapp folder, and steam.exe, once deleted everything except the two, run steam.exe, and see if issue resolved.

Ensure no 3rd party is causing problems such as hooking into app, restricting it permission, and not false positive quarantine files.

I tried running Steam in Safe Mode, but that didn't work either.

Depending on ths seettings for CCleaner, that could be your problem. That was once listed here :

Remove -clientbeta client_candidate, just install Steam normally and run normally.

I just couldn't take it anymore and created a theme because of it, because I tried every possible way I know , except reinstalling Windows.

It's possible steamui.dll corrupted file, find it, delete then run the steam.exe. without any target commands, you don't need to do any commands launch.
