Dynamic Link media server initialization error 1

[peterr24391251]

This morning I upgraded Mac Os to version 11.4 and yesterday I updated Photoshop CC to the latest version. Today I try to load an MP4 file into Photoshop, something I have done before, but I get the "Dynamic Link media server initialization error 1" error. Has anyone experienced this and is there a fix? Thx in advance!

I´m attaching the a file with the error
