We first noticed this happening here: dotnet/android#8716
It appears any Release build using -p:EnableLLVM fails with:

dotnet/android#8716 is green now, closing

I don't know why, but Maestro PRs only trigger CI like 50% of the time. It should have ~46 green checks when it's green.
I queued one, and will reopen if there is still an issue here:
