When I tried to override existing save game hanged at full saving progress bar. Game time difference is ~1 hour.
After I loaded game and tried to continue I got this error , but when I loaded working save I was able to override desired save file and .tmp file disappeared.

Thanks for the report. Based off the log file you have hardware or memory corruption issues. The game crashed in a place where it should never crash and a place I've never seen a legitimate crash happen.

I recommend running something like this and see if it spots anything: https://www.memtest.org/
