MacBook Pro, 2017 15" Ventura 13.6.3 window pops up saying: Error Message Volume Hash Mismatch

I'm getting a black screen once in a while. When watching Prime Video it just shuts down, again once in

awhile. Saved tabs on start page disappeared. I did a re:boot in safe mode, I thought it helped but then I

got the same error notification again.Also after re:boot my app 'mini note pro' was broken and now can't be opened. Not sure how to proceed. I don't know how to 'reinstall macOS on

volume disk 1s5' as the error notification states needs to be done. Can anyone help me with this issue? I'm

concerned that things may get worse if I don't attempt something. Would much appreciate your help.

Thank you.
