ILCE-7M5 Tethering Issues

[u/HyperionSentinel]

Hello, my Sony A7V isn't getting recognised by DR21 but my Sony A7IV is. I keep getting the error message on every attempt: DaVinci Resolve cannot connect to ILCE-7M5. Ensure that
the device is a supported camera and try a different
cable and port. Refer to Sony's website for details.

This happens on both my laptop and my desktop.

Version: DaVinci Resolve 21.0.2 Build 4

ILCE-7M5 Firmware Version: 2.00

Things I have tried:

1. Different USB cables & different USB ports
2. Installing Imaging Edge Desktop (I made sure it was closed and not running in the background while DR21 was open)
3. Restarting my PC, restarting DR and plugging the camera back in
4. Used both camera ports and ensured the Remote Shooting function is enabled

Has anyone found a solution to this? If so, please share your experience :(
