A Serious Error Has Occur

[dustinh10626918]

Every time I open a project... within a couple seconds the project crashes.

I have tried importing the files into a new project file, still the same.

Any thoughts on this?

I am operating on Big Sur 11.4 and Premiere 15.4.

Do you have any third party plugins?

They may need updating.

... and if this was a project that was previously created in an earlier version than 15.4 - clear your caches and reset preferences for Premiere Pro.

Any chance you have any After Effects Mogrts with Keylight 1.2 in the sequence?
