Retroarch bug on PSTV - 1.9.0 Wont Work Anymore

There is a known? bug in Retroarch on 1.9.0 for PSTV only. It will not load from playlists or load content, it will crash or close immediately. It’s completely useless now. Is there a way to downgrade to 1.8.9 or is there a working link to a vpk & data files?
