maxurl in Live crashes

I try to control an ethernet relay board with some http commands.

It does work fine in Max with the help of [maxurl] but not as a live device (Live12, Max8.6 under macOS13, 14).

In Live [maxurl] behaves erratically and crashes sooner or later (sometimes when quitting Live).

Crash logs look like this :

Is this a known issue? Any suggestions?

I built a workaround, sending TCP commands (thanks to [sadam.tcpClient]) but I'd prefer not to rely on an external.
