Hacking Question Help with NUT installer

[Tundra]

I've always used Nut+tinfoil to install my games on my Switch, but today when I tried to open NUT it crashed and now it doesn't work anymore

That's the message I get when I open it now. But I don't know what happened it used to work just fine and I didn't change anything
