Warp Stabilizer not working

Hi, 

I've been having this really annoying issue with Warp Stabilizer in AE, where the analysis initialises and either never makes any progress, or works gets a way through the analysis and then freezes. I don't have any errors pop up, it just stops working.

I'm working on AE 23.5, on Windows 11. Using H.264 XAVC S 10 bit 4:2:2 FX3 footage.I've had this issue since before this version of AE.

Has anyone encountered this problem and found a solution?

Thanks
