Issue with artifacting and red/green with my fujifilm XT3 F-Log H.265 footage

Hello all, am having an issue with artifacting and red/green with my fujifilm XT3 F-Log H.265 footage in Premiere Pro & After Effects.

I have been editing using a combination of Premiere Pro and AE (some of the footage has been edited & altered in AE) and am in picture lock and starting my color grade. However, I'm noticing weird artifacting and red/green issues in my footage in Premiere Pro vs. the footage by itself (I have attached a screen shot).

Specifically, the shadows are turning green and the highlights red. This issue gets worse as I start to color correct/grade and bring back in the shadows/highlights to the F-Log footage.

I have tried turning off Hardware Accelerated Decoding which helps *if* I re-import the footage but does not completly fix the problem (see example #2 attached).

My system specs (I have not updated to Monterey yet):

macOS Big Sur V.11.5.2

Processor: iMac (Retina, 27-inch, 2020)

Memory: 72GB 2667 MHz DDR4

Graphics: AMD Radeon Pro 5700 XT 16 GB

I am still running on Premiere Pro & After Effects 2021 because of the issues with dynamic link in the update.

Any help would be appreciated! Emma
