Navmesh generator is crashing no matter what I try. When I run it as usual, sometimes it does nothing apart for showing an empty console window for a split second, sometimes it produces a error "instruction at 0x76e0cdc3 is refering to memory at adress 0xffffffff. memory could not be read". The instruction adress is always the same, and I was unable to procure the process dump file. The other scenario is running it from the command prompt, in which case it also crashes, but with a different error message (cmd arguments and xml error report from eventvwr provided in the additional information). When I boot the system in safe mode and run it from the cmd, it gets further (to "Generating 0%") before crashing. If required, I will provide process dumps for both normal and safe mode crashes.

This issue started suddenly, I have not done anything with my software or hardware. In attempt to fix this issue, I installed windows updates, updated my GPU drivers, tried running it in administrator mode, running it with antivirus disabled, nothing worked so far.
