ProRes RAW Not Being detected in Beta

Intel i9900K

32gb Ram

Nvidia RTX 2800

for about a month now, I havent been able to edit in Premiere Beta anymore. all Prores Raw Files from Nikon Z6 and Atomos Ninja V (Only Sound works) are not compatible anymore:

- A low level Exception occurred in: Imported Quicktime (importer:81)

When I use the released version of premiere it works with the raw file, but it does take sometime to recognize it. Beta use to load right away, say 5 secs. while release version takes about 45 secs.
