Docker build hangs indefinitely after installing MSYS2

Thought I had the same issue but it turns out apparently not... Copying my message from there here below.

==========================

Same thing started happening to me yesterday with no changes on my end (been working for months up until now). Was definitely working two days ago since I have a script to force-rebuild my image daily. I see this on multiple machines and OS versions.

Tried both isolation modes (hyperv and process) and neither are currently working for me. One slight difference to the original reporter is that I'm using servercore:ltsc2022.

Still trying to diagnose further but unfortunately it's difficult to get diagnostic information from Windows containers for these sorts of issues. Trying to investigate using the information here: https://learn.microsoft.com/en-us/virtualization/windowscontainers/troubleshooting

EDIT:

Actually, I think I may have misunderstood the original issue in this thread and conflated it with mine. In my case the processes all appear to run successfully and terminate normally, but then the RUN step never finishes and just hangs indefinitely when finalizing the layer. I'm guessing this is probably a distinct issue and I misclassified it as the same as the one here due to the timing.

Strange though that it's happening on multiple machines and seems to coincide with the latest installer release. I tried rolling back to an earlier installer but that didn't help. Likely because whatever is causing the issue gets updated to the same version as in the latest installer anyway, but that's just a guess on my part so far - I need to do additional testing.
