I found something possibly relevant at https://bugs.python.org/issue42691
although there the complaint was that Homebrew built python against system tcl and the suggestion was that Homebrew use its own tcl-tk. It seems that Homebrew is correctly using its own tcl-tk since the line 5 libtcl8.6.dylib 0x000000032998c72e AtForkPrepare + 38 says that python is using tcl 8.6 and system tcl is 8.5. No idea what's going on, but it might be good to try to produce a minimal reproducible example to show to the python/tcl people.
