To weigh in on issue UE-75902, this is still affecting version 4.25. It is not specific to the foliage system, it can be reproduced by placing any HISM in a map. In my case I have mobile multiview and 64bit builds active, both of which are essential features for my development target (Quest). I have HDR rendering disabled. Error log:
