What's "1.27"? did you mean Emacs 27.1? or something else?

If it's indeed Emacs 27, then the first suspect is something you've
changed on your system recently that is not Emacs, but maybe some
library or driver.

Attach the debugger to a hung Emacs and produce a backtrace from all
the threads?

Btw, it is netter to discuss this on the bug tracker, so please use
"M-x report-emacs-bug" to submit a report with all the details.

Thanks.
