[Engine] gyro engine faults at vision loading stage (windows) #3376

I had some compile issues with this earlier, but mamaged to work around those (issues reported and closed).

Now the build was complete models etc., are downloaded, and optimisation run, the model itself will not start. Same fault every time.

Console log

2. qwen3.8-flash-next-iq3_xxs
3. install another model / change settings
   Which one? [1]: 1
   [ok] GPU: GPU 0 (NVIDIA GeForce RTX 3060, 12 GB)

Starting qwen3.8-flash-next-gyro-gyro-m: it loads about 92 GB into RAM and locks part of it for the GPU.
While it does, YOUR PC CAN BE SLOW OR STOP RESPONDING FOR 1-3 MINUTES (longer the first time after a
restart). That is normal: please wait and don't close this window - the browser opens when it is ready.
Later, closing this window stops the model.

And the window error message

So not a smooth install/setups for me trying to get gyro working on Win 11.

I tried --vision no, --vision none. No effect.
