Problem with dexed plugin

Hello sometime when i switch to a pedalboard that use dexed i have errors in journalctl for mod-host
There is also a missing manifest file but that is an other error i don’t know if related.
The problem here is … i switched to a pedalbord that have dexed from a pedalboard that was using fluidsynth as you can see. At first the modep-mod-host service crashed with a SEGV the mod-host cannot play anything … then the service autorestarted and this time the pedalboard start to work again.
Sometimes happen that the mod-host service crash and restart in a loop without starting the pedalboard. I suppose that there is something to fix in the dexed plugin since i didn’t have this problem with others … what can be ?
