GarbageBand 11 6.0.5 (428.5) Continual crashes working on Movie Track

GarbageBand 11 6.0.5 (428.5) Continual crashes working on Movie Track.

I have 8 crashes this morning. Have submitted bug reports. Very frustrating! 😠 I can layer up as many tracks as I like. As long as I don't drop in a Quick Time compatible movie file. As soon as I do that if I press the space bar to play it causes GarageBand to crash.

Anyone have any ideas? Trying to do a bit of quick work for a client, which has not lost me the better of the day....

Thanks for any help in advance!
