Problem involves pylifecycle.c and PCbuild/_freeze_module.vcxproj and something else?
Windows 10, MSC v.1900 64 bit (2015 I believe.)

After normal fetch and merge, git status says my repository is up to date. I ran >chkdsk -F on the repository drive and nothing seem amiss. I need this fixed in order to run IDLE with patches as _old _sre.MAGIC != updated re.MAGIC.

Problem began sometime after Mar 23 and before mid or maybe last April. At the time, main was 3.11.0a+. Problem continues today in 3.12.0?. I presume newish 3.11.0b1 branch has the same issue. Current 3.9 and 3.10 build fine.
@zooba Was _freeze_module patched near the end of March?
@eryksun Do you have any idea what could be wrong?
