How to fix BSOD Error 0x00000139 KERNEL_SECURITY_CHECK_ FAILURE on Windows 10?

Issue: Hey! Almost every day I get a blue screen that makes me sometimes lose my work-in-progress. This is extremely frustrating. Each time this happens, I expect that this is the last time, and there were so many last times… But unfortunately, the whole tandem of errors appear again and again. The error message says KERNEL_SECURITY_CHECK_ FAILURE, and then I have to reboot each time. Is there something I could do to fix this issue and make sure it is really the last time? Thanks in advance!
