Following Ruby install, MSYS2 and MINGW install script gets almost 100% errors (cywin heap mismatch?)

[O-J1]

What problems are you experiencing?

Inability to run the MSYS2 and MINGW install scripts that are part of "ridk install" . I have spent about 3hrs trying to troubleshoot this to no avail. Apologies if I am missing something stupid

Steps to reproduce

OS Name: OS Name Microsoft Windows 11 Enterprise
Version: Version 10.0.22621 Build 22621
Windows Defender is on with default settings (Ive seen mention of ASLR could be an issue?)

1. Install Ruby 2.7, 2.6.6 or 3.1, the version doesnt seem to matter. I was originally trying to install 2.6.6 due to an authors reccomendations
2. Use existing MSYS2 install (added the bin to path, installed latest version as of today)
3. Run 'ridk install'
4. Get a bunch of errors including references to CYGWIN heap mismatch

What's the output from ridk version?

Have you tried running ridk exec pacman-key --init
Also did you try this?
