The current model doesn't support files of this type

For the last month, I have been unable to upload files in aistudio, no matter which model I select. Most of the files won’t upload, including ppt, word. it says “The current model doesn’t support files of this type.”. I am using EDGE browser. But I used to be able to upload files, strangely enough, I didn’t have to do anything extra. What’s wrong with it? I’m very sad. Because of this problem I had to give up using gemini and switch to deepseek.
