After selecting Perforce in Revision Control, a crash occurs due to a Segmentation fault. It blames the clang update that was made in UE 5.5 since the Perforce plugin was not updated along with clang. I would be glad if this is fixed or a manual fix is suggested, it is very inconvenient to work now when there is no integration with Perforce
OS: Linux (Debian or Arch does not matter)
UE Version: 5.5.x (on version 5.4.x such a crash does not happen)
