Did a 5 lap ride this evening and everything seemed to be going OK, couple of slippage messages which basically just flashed on and off so didn’t really impact the ride.
When I finished the ride I stopped pedalling and the pause screen came up as normal however I couldn’t click on anything to save or discard the ride etc. I initially thought it was my bluetooth mini-keyboard playing up but when I tried to use my normal mouse it still wouldn’t accept a button press even though the mouse was working fine on the desktop and menus etc.
Eventually I opened the task manager to kill Zwift that way which seemed to scare it back to life and I could close it normally.
Not sure if this is a Zwift issue or a wider system issue on my PC but there you go.
