"GPIO busy" error when Argon script is running

I have an issue with my One up. With the argon one up script running, any attempt to use the gpio pins results in an error from lgpio “GPIO busy”. It’s a simple bit of code to turn an LED on and off. I’ve tried using Gpio 17 and 27, same error. Uninstalling the script fixes the problem. Has anyone else seen this issue? All I’m interested in Is the battery status. Is there any other method I can use to see it?

I’m running the latest raspberry pi OS

Edit - Investigating further I realise this is not an issue for this forum. Reddit is full of gpio busy errors so it’s clearly not an Argon one up problem. I verified this by booting from another copy on an SD card and no issue.
