Revit could not load C:\Program File\Autodesk\Revit2022\IntflFC.dll

[matthew.harper15]

I can't open any revit file due to this error message "Revit could not load C:\Program Files\Autodesk\Revit2022\IntflFC.dll" Revit has been working fine up until this point.

Has anyone else had this issue or know how to fix?

Thanks
