Pinwheel freeze during Gausian Blur editing

[Ryan32780300gx57]

After completing the automated mask-tracking feature, when trying to make adjustments to the mask key frames, the pinwheel freeze keeps happening causing me to force-quit the app to continue. Also, is there no way to use the sequences or projects from this beta version in the regular version if this keeps happening or is all progress/work stalled out?

You cannot open a 24.1 project in 23.6 nor in any older version.

You have never been able to open any project being beta or public in an older version.

Furthermore, you can however open a 24.1 project in 24.0 (install the beta or wait until it goes public).

There are YT video's on how to convert to an older version.
