Latest couple of AME beta releases crash constantly

I'm currenlty on AME 23.1x1, and this version (as well as the previouys version) ALWAYS crashes as soon as I start an encode.
1. Load up AME

2. Drag a ProRes QuickTime into it

3. Apply the poreset "H.264 - match source"

4. Click on the preset to adjust it

5. Turn off the 'export audio' checkbox

6. Click OK

7. Crash - every time

Workaround - use an older (2022 or 2021 release) version - they work fine.
