Since Psych 5.2.5, the following error has started occurring on Windows environments with Ruby 2.7:

Looking at the stack trace, it seems that the changes in #695 may be related. This issue also occurs in the latest stable version, Psych 5.2.6.

It seems MSYS2 issues.

see ruby/setup-msys2-gcc#26 (comment)

MSYS2 aggressively updates GCC and that environment in recent weeks.

Ah, that looks like the issue. I'll close this as a Psych issue. Thank you for sharing the information quickly!
