Hey, sorry for the delay. We deprecated the boot cache in UE 5.0. Its original purpose, 11 years ago, was to mitigate the seek time overhead on hard disks. With solid state drives being the norm for years now, the benefits of a “boot cache” are outweighed by issues like the one you are reporting. I recommend removing the boot cache from all of the DDC graphs in BaseEngine.ini and/or DefaultEngine.ini.
