CSR private key tab crashes request and mmc.

Question

I create CSRs for the company from my workstation Wiindows 11 21H2 22000.527. Recently when attempting to create a custom request/legacy key csr; when filling in the details and i click on the private key tab it crashes and closes the request and certificates mmc. This happens for both user and computer certificates mmc. Does anyone else have this issue or know where i can look for a fix? i'm currently using another machine to generate requests but would like to move it back to my admin machine.

Hello @Ross, Kevin

The fault module that is causing the crash is Protector64.DLL. This is a Library that is related to the product Morphisec Endpoint Threat Prevention.

The recommendation would be to get in touch with the software manufacturer for assistance or orientation about any fix, but from the operating system perspective, it should be enough to disable or uninstall the software temporary or try a Clean Boot:
