Problem Gmail problem xiaomi mi 10 t lite


Hello, I have a problem with my xiaomi phone, more precisely, I cannot in any way attach a file through the gmail application, I also tried to select a file from the application to send it, I select it, but it does not appear in the email on which I want to send. I also tried to go to the files, to select the file, to send it via gmail, but it says file not accepted. Does anyone know how I can fix this? I deleted all data from gmail, reinstalled it, but to no avail. I can't send absolutely any file, be it pdf, JPG or any other format. Thanks
