[Help] Loading Error

Can anyone help me fix this issue? Mudfish was working fine though but for some reason now it just won’t work. Any help would be appreciated!

Did you try to use mudfish v4.6.1 which found at https://mudfish.net/releases/ link? I’m not sure that this issue is caused by using mudfish v5 but please test with it when you get a chance.
If you want to use mudfish v5, I think Debugging issue for Mudfish v5 link is helpful too to debug your issue.
