part two  

Thanks for the recommendation David! 

You could try to lock the joystick by pressing and holding Menu/Ok until a lock symbol appears. You can unlock the same way.

sometimes happen when connecting with remote app , it's more likely the camera remote app issue ,rather than camera software issue . the only few times i got the same freezing issue was when i connected with the remote app . never happened otherwise , not even once . hope this helps . have a nice day ahead !

Same expect according to Fuji, it's supposed to work on my version of OXS (Mojave). Installed the latest version of X Webcam 2, did a firmware update on X-T30, changed the USB connection setting to USB Webcam, connected the camera through USB (no hub). The camera is not recognized and doesn't show up under available cams. Also, Fuji X Webcam software's entire interface is grayed out.
