Unable to export Mocha Pro clips from AE/AME

I work with 360 video and I'm using Mocha Pro in AE 2020.

I'm tracking, removing and checking the correct boxes, but I'm totally unable to export the final clip.

I can't export directly from AE, I can't export through AME, I can't do a RAM preview in AE.

Tried exporting ProRes, H264, PNG seq, but nothing seems to work.

Exporting works well until the point where my effects kick in, then it just stops. It doesn't give me an error, but the export's just not progressing at all.

Has anyone else encountered the same problem and what's your solution?
