I'm still searching for the reason my favorit program CALIBRE is crashing! Now i started Calibre 9.3 in a Sandbox, and before the crash happend, i got the note -Microsoft C++ Runtime Library (please see jpg).
So i reflected, what may be the reason for that C++ runtime error.
First I uninstalled "everything" (Software for very quick searching!), and after a restart and updating Calibre, Calibre 9.3 was running without any crash! I tested it only for about 5 minutes (anxious), but it looks very fine!!
At the update from 8.55 to 9.3, after uninstalling everything, Calibre told me to restart the PC, because Calibre made changes that need a restart! Calibre did this not before!
So i hope i found at last the reason and calibre will run perfectly on my PC as usual!
