Help!! Crashes!! [Assertation failed: Uniform Buffer] etc...

All it takes is selecting the Actor which the Camera is parented to in the sequencer and Unreal crashes.

This is killing me. I work exclusively in sequencer and was bold enough to complete the last 80 hours of work in UE 5.5. Unless there is someway to migrate backwards, which I know there isn’t, I’m stuck crashing every 5 minutes, or recreating my work in a more stable version.

I could troubleshoot this further, but based on other reports, I don’t think the level of complexity of my scene or animation edits is the culprit. This seems like a low level caching issue, but I don’t really know.

Any help from Epic? Pretty devastating. THX1

UPDATE:
Decided to start a sequence from scratch with a barebones setup. The significant change was to remove my camera from the rig hierarchy (CTRL_Mover > CTRL_Cam > CTRL_Offset > CineCam). This SEEMS to be stable for the moment.

Strike that - A simple Cinecam, with a single plane parented to it seems to be enough to crash it? I can’t be sure.
