Warp stabilizer extremly slow on Sony HLG footage whilst it's really fast in AE

A while ago I noticed that my footage was taking absolute ages to stabilize using warp stabilizer in Premiere Pro. Only yesterday I realised this was happening ever since I switched to the HLG gamma in my Sony FX3. I noticed that AE has no problem stabilizing said footage. A comparison:

- 250 frames of HLG footage in PP take 9 minutes to stabilize

- 250 frames of HLG footage in AE take 45 seconds to stabilize

We're talking about a staggering 12x difference. Every other gamma (Movie/Cine/S-log3) flies through warp stabilizer in PP without any problem. Since it's only a problem in PP and not in AE I assume it's a bug. Is this something that I'd be able to fix on my end or is it a limitation of PP?

Some extrta info:

I had the same result wether it was 10bit 4:2:2 footage or 8 bit 4:2:0 footage HLG footage. Changing the color mode from BT.2020 to Rec709 in the Sony settings still showed the same result.

The PC is an i9-10900x with 32GB ram and a Quadro RTX 4000 card.

Have you find a solution? I'm having the same problem in PPro 24. It takes minutes to stabilize shots that before took seconds

I've also encountered this problem and noticed that when I switch the color profile of the file in the project bin in Premiere Pro (right-click on the file or all files > Modify > Color > switch from 'Use Media File Color Space' to 'Overwrite > Rec 709'), it works as it should, analyzing Warp Stabilizer quickly. However, this changes the colors of the file. So, what I do is modify the color space of all files, apply Warp Stabilizer where needed, and then switch the colors back. It's frustrating, but hey, it works... although it slightly disrupts my workflow.

Adobe should definitely look into this.
