It's just insane. If there a way to post a video I can post one for you guys to see how it behaves.
Everything was working normal until the 11th November exactly. After that date all start to behave like this.
You can use any video hosting website, even YouTube will do (
set the video as "unlisted"), then paste the link to your reply.
What's happening isn't normal for a standard wallet and AFAIK, isn't a known issue.
I can only suggest to backup your wallet and seed phrase, then reinstall Electrum.
Before installation, make sure to verify it (
instructions) before proceeding to make sure that it's not corrupted or a fake version.
