I can suggest you a quick trick here, if it won=92t work I will help you fu= rther which might take a while. Follow the steps below. 1. Go to refi shell 2. Reconnect -r 3. If the sysytem hangs. 4. Try to update your BIOS/UEFI to latest (as I had noticed the eariler BIO= S/UEFI had some some problem which normally gets fixed with updates). 5. After update once again try Reconnect -r. 6. If theres a no hang restart the system and now you can try your app or j= ust give disconnect in uefi shell. 7. If still I doesn=92t work you can ping me I might suggest the other way = around.
