ProRes with Alpha imports with error

Using the latest Premiere pro (V26.2.2). Just created a simple logo animation in AE and exported it with Quicktime (.mov) using ProRes 4444 with an alpha channel (RGB + Alpha).

When I import the file into Premiere Pro, I instantly get a ton of red error messages that say ‘Error retrieving frame’ and then it lists a bunch of frame numbers and mentions the clip I imported.

I’m working on a commercial for a large client with a tight deadline. I’ve never experienced this before. Been working in Premiere and AE using this workflow for 15+ years.

I also tried the animation codec with Alpha and got the same error.

I don’t have time to troubleshoot Premiere bugs.
