[MPM] CI Fails Regularly

[matekelemen]

The MPMApplication regularly fails at the (single-rank) python test phase with no message whatsoever.

 Running MPMApplication tests
...................................................................................ss......D:\a\Kratos\Kratos\bin\Custom\applications//MPMApplication/tests/test_MPMApplication.py
Completed MPMApplication tests with exit code 1!

I haven't checked but I assume it's some sort of memory corruption because unittest can't even generate an error report. If you have trouble finding the issue, I recommend taking the time to compile with ASAN enabled (-fsanitize=address) and sift through the report it generates for each test case separately.

Here's a complete report of a recent Windows CI failure from #12254: ci_log.txt
