You may need to be more specific in your title or post about what aircraft you are experiencing the crashes with.
It sounds like you are talking about the Fly By Wire A320? My first guess would be to clear out your Community folder apart from the FBWA320 and see if it changes anything (possible mod conflict). Then maybe swap to the stable version of the mod and see if anything improves?
Experimental is prone to bugs and I don’t believe they offer support for it, as it is for testing purposes. They welcome feedback and bug reports though, probably via their Discord.
