How do I solve this movement issue?

I have a simple ball pawn that I move with a physics thruster. When it moves quickly it hitches and jerks like this: 2022-03-16_15-37-52.mp4 - Google Drive

So I thought the answer would be to turn on substepping which looks like it solves the issue but now it crashes. It looks like the crash occurs when it hits a wall, usually when it goes fast: UE5Crash2022-03-11_10-44-39.mp4 - Google Drive

Here is a crash log: UECC-Windows-713521D645F492B3E402E0B500ECB8AC_0000.zip - Google Drive

So I have a choice, leave substepping off and figure out how to stop it from hitching or turn substepping on and figure out how to stop it from crashing.

What would you do?
