ValueError: invalid literal for int() with base 10: b'\x00\x01_\x00\x00\x00\x00'Interestingly, after implementing the workaround below, the initial warning still occurred. But after changing the FOV setting once, that warning went away on subsequent runs. I think the factory setting didn't match any of the menu options, but I don't know what it was set to. After implementing the workaround, all FOV menu settings work and no errors or warnings are emitted.
