created branch 123-network-share-mounter-crash to address this issue

changed title from Network Share Mounter crash to Network Share Mounter crash EXC_CRASH (SIGABRT)

changed the description

created branch 123-network-share-mounter-crash-exc_crash-sigabrt to address this issue

added label::bug label::confirmed label::critical labels

changed milestone to %Network Share Mounter Version 3.0.4

I believe the problem lies in a race condition: Even though os_unfair_lock is used, there could still be race conditions, especially when multiple threads access the _shares array simultaneously. Solution: Use an actor for thread-safe accesses in the ShareManager class.
