Description

Within UMoviePipelineBlueprintLibrary::UpdateJobShotListFromSequence we are experiencing an editor freeze when launching an MRQ render of sequences where a camera is unable to find a valid possessable using the ParentGuid.

This is using the MovieRenderPipeline plugin on Engine version  5.5.1.

A while loop starting on line 577 of UMoviePipelineBlueprintLibrary::UpdateJobShotListFromSequence is unable to exit, as no FMovieScenePossessable* is found. Due to the while loop having no exit logic, our editor is stuck hanging.
