Session name length past 40 characters hangs

[haberdashPI]

If I create sessions names longer than 40 characters zellij hangs.

12:32pm ❯ zellij attach -c '123456790123456790123456790123456790'
Bye from Zellij! 
12:32pm ❯ zellij attach -c '1234567901234567901234567901234567901'
^C⏎

The first command properly opens zellij, while the latter hangs indefinitely

This occurs on MacOS 14.3.1 regardless of the terminal I'm using (VSCode or iTerm2).

In my case, there is a different limit. It's just 19 characters. 20 character long session names cause the session to never start.

$ zellij attach --create 1234567890123456789
Bye from Zellij!
$ zellij attach --create 12345678901234567890
^C
$ zellij --version
zellij 0.40.1

I want to add that this behavior just appeared out of nowhere, I didn't update zellij, only restarted my mac. It was temporarily resolved by updating to 0.40.1, but only for a few minutes.
I also tried deleting ~/Library/Caches/org.Zellij-Contributors.Zellij and restarting once more, but that doesn't seem to have helped.

I thought this might've had something to do with maximum path lengths, but no:

$ cd /Users/feuh/Library/Caches/org.Zellij-Contributors.Zellij/0.40.1/session_info
$ cp -r circular-oboe AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
$ tree

$ zellij ls
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA [Created 1day 18h 38m 52s ago] (EXITED - attach to resurrect)

erudite-hill [Created 1day 13m 10s ago] (EXITED - attach to resurrect)
$ 
$ zellij attach AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
^C
$ zellij attach circular-oboe
Session detached

Interestingly, the character limit seems to differ depending on the environment variables.

$ zellij a -c 12345679012345679012
Bye from Zellij!

Don't have more time to dig into this right now, but maybe that's a clue already?

Have the same problem on MacOS. For me it's 36 characters. I have no idea what is defining that length.

It's not a problem on Linux.
