I have no troubles with the Track Matte effect in projects created in the 2022 version. So ... this would seem to be an issue from project migration. So, some troubleshooting questions seem useful.
- If you create a project in 2022, and add the Track Matte effect, does it work properly?
- When migrating the project, did you create a new project in 2022, then from MediaBrowser, select the old project file and Import the assets to the new project file? This is by far the safest, most reliable way to migrate. "Opening" an old version project in a new version is prone to issues.
- When opening the project in 2022, did you first delete all cache files? That's another area that is rife with troubles.
