OP you can try updating Sparrow wallet that just released new version 1.7.0 few hours ago, with lot of bug fixes and new features.
I am not sure if this will fix all your issues, but you could also contact developers or write your issue on their github page.
This is a cool wallet and best alternative for Electrum I found so far:
https://github.com/sparrowwallet/sparrow/releasesI just updated sparrow and still won't connect. I think I'm going to try completely uninstalling Bitcoin core and sparrow and then reinstalling them and see if that works.
