During handling of the above exception, another exception occurred:

Thanks <3

Start in gui_v1.py, especially load() around lines 157 and 195 and launcher() around line 224. Reproduce starting the realtime GUI and inspect the JSON loading and input-device selection paths shown in the traceback. Done means the GUI starts without the reported JSONDecodeError or ValueError.
