New user. Attempting to stabilize a clip (a .MP4 from an old GoPro Hero 4 Silver). Crash occurs approximately 10 after requesting the stabilization. clip was on a fresh project (this clip being added and the stabilization request were the only actions taken) as I am new to the program. Crash appears to be repeatable. Also note I am below average skill level as far as Linux expertise goes.
