Enhanced metadata not able to make changes

Hi, 

I'm having issues after an update to a newer version of power bi. I tried downgrading but unfortunately I wasnt able to open backup file, must have saved the file before realising in the newest version. 

I'm getting an error while trying to upgrade to the enhanced metadata feature saying it can't find certain tables. This is because of a broken measure. I'm not able to delete or update the measure, so I'm stuck. I cant use my report anymore.

Is there a way to disable this metadata function like in the older versions? I know it's my own fault for writing over a save file but I can't do anything about that anymore. 

Thank you in advance!
