import a project

Hello Adobe users

I wanted to import a project, as I have been doing for years, via Media Expres from Blackmagic into the latest update (24.3) of Adobe premiere, this did not work or was very slow and also hangs, the settings in Media Expres have been the same for years, 1080i50 and in avi motion jpeg, I then used the previous version of Adobe Premiere (24.1) again, and this worked fine again, this happened both on my desktop PC and on my laptop, how could this be that the previous version does it work? I tested this twice and got the same result

Kind regards
