I just did a reinstalled and it is working fine now. I think it is possible the first installation was corrupted. I verified the signatures so we are all good.
A user has reported a same issue in
electrum page on GitHub. His problem was also solved after re-installing electrum.
Given what I read in that thread, seems that this happens when you install the new version of electrum while the old version is running.
The windows installer doesn't give any error before it starts to delete old files. This causes some old files that are in use to not get deleted.
Windows installer give error once it starts to overwrite files that are in use. The user closes electrum and click on "retry". The installation is completed but some unnecessary files from the old version still exist.
