OCLP Sonoma iMac issues after power cut

I had a couple of sudden power cuts while my iMac was on, and when I cam back it was looping in to logon screen, then come back to the logon screen after few minutes of use. When I'm in, it works very slow and my external monitor lost its resolution and its fussy.

Is there a way for me to restore everything back to yesterday (I have a time machine backup).

If so, can someone give me a step by step guide?

Please help!!
