Quartus Prime Pro 25.1 Crashes Randomly

Hello cblixt, thank you for your response. I’ve tried installing the patch, and it seems to have solved the issue—at least the two compilations I ran after installing it completed successfully, and no text file was generated. However, I don’t understand the origin of the problem or how it’s possible that it also affects such an old version of Quartus as 13.1, which I use for some older FPGAs. When I try to compile a project for those, a similar error appears, and the program closes.
