I don't understand what you mean by "removing directories other than
C:\WINDOWS or descendants".  Why do they need to be removed?  And how
did you remove them?

Why are you changing the system PATH?

What happens if you change PATH to include the two addition
directories, c:\msys64\mingw64\bin\ and c:\msys64\usr\bin, before you
start Emacs, and then run GDB from the shell buffer without changing
PATH inside the shell buffer?

Please also show the contents of these two directories you add to
PATH.  Maybe the reason for this is something in those directories.
