Repeated Crashes - Catalina 10.15.7

When did you replace the stock drive with the Samsung EVO SSD?

I also see some weird stuff in the diagnostic section that I have never seen before.

At this point I can only suggest trying Safe Mode followed by a restart.

Then if that doesn’t help, then perhaps reinstating the macOS might.

I suspect the hard disk portion of your Fusion Drive is failing which is causing the kernel panics. Please download the evaluation copy of DriveDX and test the Fusion Drive. If any errors appear, that confirms my hunch. As your computer is classed as obsolete, you can take it to an independent Apple Authorized Service Provider for repair or you can get an external SSD, clone the internal drive to the SSD and then use the external SSD as your primary drive.

Another option is to simply replace the computer, it is very close to 10 years old now and cannot run current versions of Mac OS. New Macs are considerably quicker than your 2013.
