The problem was solved yesterday with a change selected & downloaded the new file. The second problem of connectivity was solved by the restart total system.
Can you clarify which second connectivity issue are you referring to? In my case, I have some occasional network issues with my Mac if I connect it to a dock, but this applies to the device itself and is not exclusive to Electrum. I find that with 12.2.1 my network is relatively stable, so in my case, it is probably a dock incompatibility issue with the latest mac.
Yes of course, Official Mac users required an update & restart fixed all bugs,

Somehow you're a Hackintosh user who must check the sound adapter, network adapter,- keyboard, and graphics, To solve all bugs required "OpenCore Configurator" & adapter .kexts file, supposing is not resolved the bugs. types adapter model number go to GitHub and search adapter .kexts file.

In the final step, if the solution does not fix all bugs then all the adapters that support (macOS) they should be bought and used.
