GUI for ganglion hangs at Starting Session [resolved]

seignseign Berlin
edited February 5 in Ganglion

I´m using the Ganglion board with the openBCI GUI on a Windows PC. The software gets stuck and hangs when trying to start the session. It says ´Starting Session´ but never actually starts. I tried some things:

Happens on Windows 10 and 11, both with and without running as admin.
Happens with two different bluetooth receivers, and on two different ganglion boards. All of those do actually function properly on different windows PCs.
Happens with both the GUI application standalone as well as through the processing app.
Tried reinstalling several times, no luck unfortunately.

Would you have any idea what it could be or what I could try?
Thanks!!

    Just solved it! The audio NullPointerException error was more serious than I thought. I don´t need it, but simply plugging in a cheap pair of speakers solved all the issues! I guess the gui was trying to play sounds during connection with the board. Without speakers it got stuck there
