TeXmacs crashing when opening

For some weird reason, I’ve got a recurrent problem of TeXmacs on my computer. Just recently, every time I tried to open TeXmacs, the program crashes and produces the following error, see image attached. I’m not sure what’s causing it and how to get rid of it.

I have tried uninstalling TeXmacs and reinstalling, but the issue is persisting. I have also made sure to remove the /user/.TeXmacs folder, but this does not seem to help.

I think I may have gotten rid of the problem as soon as I shut down the new Universal Control feature between Macs and iPads

Actually, the problem still persists. Not sure what’s going on. If I wait a little while, then TeXmacs starts up again, but then crashes if I open more than 3 windows.

Not clear. Can you try to launch TeXmacs from the Terminal (not with “open”, but calling directly the executable in /Applications/TeXmacs.app/Contents/MacOS/TeXmacs and see what happens?
