Unable to open 2023 AE file in AE 2024 (Error 33::7)

[defaultgy7fo4nhyi9w]

Hi there, I'm having real issues opening a 2023 AE file in AE 2024. My files were auto-saved and these won't open eithet. I can only open previously auto-saved AE 2023 files in AE 2023 only - not ideal! 

The error message 33::7 appears followed by error message 25::0. I have attached these error messages for reference.

Does anyone have any solves for this. The work took several weeks and worried its all been lost. 
Thank you!

FIY to those experiencing the same issue. I have managed to solve the problem. I had a .c4d file in the AE file (clue in the 25::0 message above/Cineware). I opened the AE file  in AE 2023 deleted the c4d file and resaved. AE file now opens in AE 2024.

I have the same problem, but no c4d files in the project. Any other hints?
