Crash on opening a score that uses Kontakt VST instruments (via Element)

I have been using KushView Element to assign Kontakt VST virtual instruments to parts in my MuseScore4 scores, and all instruments play fine initially. When I save the file there is no error. But when I try to reopen the file, MuseScore crashes and closes. Just before the crash, the score window is drawn, the mixer is populated with the instruments, and is a small "Progress" window appears for a millisecond with just the word "Converting" in it. Then poof! it all goes away. No matter how I try to open any score I have saved that has Kushview Element graph that includes a Kontakt instrument--whether from with the app or from the Finder--Musescore always crashes. I have replicated the behavior with multiple scores that work fine otherwise. I have also confirmed that the crash does not occur when using Element instruments that use VSTs other than Kontakt. There appears to be a bug in Musescore that only hits when initially opening a saved score that includes a Kontakt instrument. I have a large (and expensive) library of Kontakt software instruments, so I hope you can fix this in the next version! Happy to provide any diagnostic files if that would help. I'm using a 2020 iMac with Sonoma 14.2.1 and Kontakt 6.2.2.
