Design ssrs can never find the report style anymore

I can still click design ssrs and download the report style, but if I try to preview it, I get this error. Same error in every environment, every report. There is nothing wrong with these reports. I can run them and they generate successfully. They are definitely marked valid for the company I am in. It doesn’t matter if its a custom style on a standard report or a fully custom report, it gives the same error. Also doesn’t matter where I save the rdl locally, have tried in documents and in a temp folder directly on the C drive. Is this working for anybody else?
