Problems with Studio and Premiere Plug In

Hi I'm having problems editing X2 video on Studio (vers. Winx64 3.5.5)

I first tried Premiere Pro (latest Vers14.7.0)

X2 files Source Settings are incomplete, it lacks accessory option for dive case stitching . 

Therefore I'm forced to stitch inside Insta360 Studio. Here there are additional problems.

Aquavision makes exports unplayable and causes Studio to crash.

Please help.
