Can't provide the level of detail as above, but CCleaner (same version) all of a sudden is unable to complete a cleanup using the "health Check". It slowly creeps up to about 66% progress, then simply closes. If I re-run the scan it finds the same number of tracking cookies and files to clean up, so it isn't doing anything. If I do a Custom Clean it appears to work.
PC, running Chrome browser. Problem first noticed 11/14/2020
When the health Check is complete, choose to exit Ccleaner. Windows diagnostic apps are forced to close. It may be that the program task cannot be closed normally.
Same crashing happening here, running Win 10 Pro, 64-bit, v1909. It crashed once the first day I updated to this version, 4 times the next day and once already today.
I only use the Custom Clean option, rather than the Health Check option. My error list (below) is identical to the one Bryanlky posted in the OP:
