He might be using Ubuntu 18.04 which I heard super buggy. So there might be issue from the OS that cause wallet crash everytime he close the Electrum.
Unlikely

I use the v4.0.4 electrum of windows, when i closed the electrum, then crash infomations came up
More likely something with his Windows setup causing issues... I am not having any issues with 4.0.4 on Windows 10 Pro 64bit, version 2004.
I had more issues just downloading and running the installer due to Windows defender popping up with all the usual warnings about it being an "uncommon download" or some such bullshit. I reported it as safe etc, but the same thing seems to happen with every new release
