I noticed you said you had reinstalled Luban.  
I have just had the age-old problem of "Something went wrong. Please reload the app”.  
Even though I had reinstalled Luban, and even tried the previous version, I still had the problem. That was until I searched the forum and found this:

> [@Luban 4.7 "Something went wrong. Please reload the app"](https://forum.snapmaker.com/t/luban-4-7-something-went-wrong-please-reload-the-app/30488):
>
> Updated to Luban 4.7.0 and now I get this message at startup: “Something went wrong. Please reload the app” I’m on Windows 10. I had not upgraded since 4.4 because Luban has always been problematic with every upgrade. I have tried uninstalling and reinstalling the app with the same result. Any suggestions on resolving this issue would be appreciated.

It seems to have worked for me by deleting the suggested folder, but I can’t be sure I didn’t delete any of my personal set-ups or tool profiles, etc.
