CATIA Composer crashes

Hi all

All our CATIA users are having issues with it crashing frequently. As in, at least once a day often multiple times a day. All of them started with VCRUNTIME.dll causing the crash. After some discussion with our software partner, I did an in-place update of Windows. Basically re-installing Windows without losing all files and programs. It went well for 2 days, until it started crashing again. This time Litkernel.dll being the cause of the crash. A few weeks later VCRUNTIME is starting to pop-up again in the dump files. I have no idea what changed...

Everyone is on version 7.9.0.22064 and is sending me the same crash logs. Does anyone have any idea or experienced the same before? I'm only at the company for a couple of months but apparently this is a long going issue.

Thanks for any help or tips!
