Do check out the following post. I've worked with most of the media users are complaining about. In Pr2022 there are several major changes to color management options and to Premiere's default behavior with a number of Sony, Canon, and probably Panasonic Log media formats.

If you don't understand and follow several steps, you'll have troubles. If you do, it works except perhaps for the M1 Macs, there may be a bug there.

FAQ: PremierePro 2022 Color Managment for Log/RAW Media

And do understand ... they are moving the app forward with these color management options. They have to do so, and we users will have to adapt to having more options. Between so many cameras offering HLG or PQ recording options, which a lot of people are using, and many new phones defaulting to recording in HDR forms, the nature of the incoming media is changing rapidly.

These changes are not going away. I have a big problem with the implementation. To me it is piecemeal with options spread through too many locations for quick and accurate user workflows. But the changes are entirely necessary.

I've not had a single clip that I couldn't quickly and relatively easily get working correctly on both SDR (standard Rec.709) and HDR timelines. And I've tested "problematic" clips from quite a few other users. That supposedly could not work within Premiere no matter what they did.

There were simply a couple small but required steps they didn't know about.

And ... there are a lot more troubles with projects brought forward from 2021 simply because there are enough default changes in the way Pr treats certain media. Especially Log media. Fixable, but again, you gotta know what to fix.
