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.
Im 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)
Have you considered trying to use
"electrs" instead of EPS?

I have "electrs" running in
an Ubuntu instance using the "Windows Subsystem for Linux" inside of Windows 10. I then have Electrum 3.3.8 (Windows 10) connecting to my local "electrs" server using
--oneserver and
--server localhost:52001:t commandline options.
"electrs" reads the block info from my Bitcoin Core full node install (0.18.0 running in Windows 10).
NOTE: I have not tried this setup using Tor.
