None of the versions my PC accepts. Is there a way to compile it in AVX (not AVX2), just AVX?

I have this:

1. DON-SSE4.1
2. DON-AVX2
3-. DON-BMI2
3*. DON-BMI2-COMP
4-. DON-AVXVNNI
4*. DON-AVXVNNI-COMP
5-. DON-AVX512
5*. DON-AVX512-COMP

or

DON-SSSE3-POPCNT
DON-SSSE3

Thanks

This is a singular occurrence. Then the engine shuts down by itself.
