Unexpected end of JSON input

Hello there,

Does anyone know how to solve this error?
When I start Photoshop I get the error (SyntaxError: Unexpected end of JSON input) and I cannot use texts, I have uninstalled it and downgraded it, nothing works.

Thank you very much

Do you have any 3rd party panels/extensions installed?

The other thing to try is restore your preferences using this manual method. Does it work correctly?

If that doesn't solve it, you can quit Photoshop and put the Settings folder back.

I only have a font script that I have been using for years with no problems.

In the end I have succeeded,I told the uninstaller to delete all my settings and that way it no longer gives me that error.

Thank you very much for your help, very kind Jeffrey.

Best regards.
