Tkinter causes SIGSEGV and system crash - how to fix?
Turns out for some reason the standard version of Tkinter (8.6.*) was no longer functioning correctly. I found https://bugs.python.org/issue34927 and soon after updated to Tkinter 8.6.9 (conda forge), which seems to have solved the issue.
I have the same problem (for a long time I have to use a linux machine to run my script). However, you can potentially solve the problem with conda install -c zeus1942 tk this is the Tkinter 8.6.10 latest version as the time I comment. It solved my problem, but not always.
