I'm also still getting this low-level exception error in Premiere 2020 v14.9 so this has still not been addressed after almost 5 years. Adobe!! What are your engineers doing about this??!! I've been well aware of the basic uselessness of actually using this transition, although it is a welcomed "quick" fix to have in my back pocket when editing documentary interviews with limited broll or the need for an edit in a spot that would be distracting to cut away from the interviewee. I've found the work around by @derekg16025711 to be very helpful but yet discovered another related bug, where after exporting a video to patch my morph cuts, Premiere continued to give me an error and increased render times almost 10x, just cause the morph cut was in the timeline. The ProRes .mov patch video was on the video track above it, so there was no reason for Premiere to attempt a render on the morph cut. However Premeire still choked on this and wasted 4 hours of my time today trying to get a 6 min edit to my client. Adobe, where can I send the bill for the time you wasted today? Also will you please finally fix this known issue with Morph Cut, otherwise you might as well just drop it off the next release.
