I randomly get some error which I cannot describe

I'll add a screenshot - but again, sometimes it works sometimes not..

Looks like file is corrupted.

So sometimes the file generated is corrupted and sometimes not?

I have to point out here - I can do the same 2 or 3 times.. and sometimes it works with no error message and sometimes the error message comes.

And my RAM and HDD I used apps to determine if there's bad areas on them - seem to be both 100% fine with no errors.
