I have and old version of electrum wallet portable version 1.7 running on windows 11 that i had being using since 2013 till date but after changing my internet modem.
Why don't you first update with latest version of Electrum wallet and replacing exe file with one you have on your device?
Using portable version is not recommnded for regular users, and it's better to use other available options or Electrum with Tails OS.
