Hi Tkinter,

I wanted to call a Tkinter-based Python script through gRPC.
Although it works perfectly it crashes on macOS.

I wonder if the expert on this list could kindly shed a light on this
StackOverflow issue
<https://stackoverflow.com/questions/69513599/tkinter-crashes-when-called-through-grpc>
My machine setup, the crash log, and the detailed secenario with code
samples are present in the issue text.

Many thanks,
Beinan
