Okay, I would like to get this issue resolved. The Electrum Multisig wallet is working fine but I would like to get Electrum to run on a Bitcoin full node.
I’m offering 1M sats (0.01BTC) to anyone who can get EPS to work on my laptop. Contact me via PM to arrange details.
Here is my setup:

Windows 10
Electrum multisig wallet (version 3.38)
Bitcoin Core (0.18.0) configured to run via TOR
TOR browser (8.5.1)
