neither Start Menu opening nor any of the settings in windows 10

hi friends.

as far as i can check, no new update has been installed in last 2 days on my system running Windows 10 22H2 build 19045.5487. no hardware is changed too.

today suddenly the Start Menu started misbehaving / is not opening. if it opens after 2-3 clicks, it closes itself.

It is not working in any of the user accounts including admin.

none of the settings in windows 10 is opening. it shows the load window with setting icon in middle and then it closes itself.

i tried sfc and then dism methods told by many forums and ms staff. sfc showed some error and dism said all files replaced successfully.

i tried explorer restart.

i tried start menu package refresh method using dism told by many forums and ms staff.

i tried index rebuild too.

i created a new admin user but it is not working in that as well.

checked but no updates available for display.

no key on the keyboard is stuck. rather it is working fine.

mouse too is working fine.

ms settings is not getting open if run from powershell / run.

updates is not getting open.

What could be the reason / options to correct? the option to reinstall is always there but is there anything else i missed? thanks.

PS: working fine on windows sandbox

Any restore points created on system drive to fallback on? If so, try restoring to a previous state. If restore point is not opening, open cmd as admin and run rstrui.exe
Try clean-boot approach. Refer google how to do clean-boot if you are not aware. You can always revert back.
Scan your system for any malware/viruses

thanks buddy. i forgot system restore since i don't install software / hardware frequently. it failed and then worked when i ran it from recovery environment. that issue is gone but browsers stopped working. installed crome with much difficulty. unable to uninstall firefox so removed all entries from registry and removed the folder. creating new desktop links for different crome profiles right now.
