Hi. I was using the lightning network with Electrum 4.0.3 in linux

I opened a channel, sent a few payments (first failed, a couple worked, then the last 3 failed) and decided to close the channel Now my wallet seems to be stuck showing this small window that says "Please wait" and I can't click anywhere else on the actual Electrum wallet behind the pop up. It's been stuck there for about 45 minutes and I haven't tried to close it or anything.

Here's a screenshot



Any help on what to do here would be great. thanks!
