I would boot up under an external bootable drive, run Disk Utility - First Aid to fix any drive issues. Then, run a good anti-virus and malware app with the latest definitions to make sure you don’t have something else lurking.
The next action would be to remove the SSD place it into a OWC case hooked up to a second system then make a backup of the users stuff to an external drive. Then reformat the drive and install a fresh copy of MacOS (same as what the system had) reinstall the SSD is the system working now? If it is then restore the user accounts, apps and users data.

In reviewing your crash report you have a deeper problem. I’m suspecting you have a logic board issue. Are you able to get diagnostics to run?
