Thanks for your detailed explanation and solutions.
I will aviod opening Python scripts in $HOME directory and use git to
manage my python project. For the single file, just put it in an empty
directory aslo works as expected.
I enjoy using M-x eglot and never use eglot-ensure.

C-g sometimes can "unfreeze" Eamcs and stop the find program.
