Hi, I've got something similar, when i browsed to the path of the .rdpv file, there were 2 files with the same name, one is name for example, session12012022.rdpv and the second one session12012022_1.rdpv. the first one was 1ko and the second one a lot more. i just renamed the first one .old and removed the _1 on the second one and now it display correctly in the playback.
Hope it help
