i havent been able to download anything since august 2021, and it keeps saying file_security_check_failed or something like that. idk what happened and what caused it but some of the things ive done havent helped and i can only download stuff on firefox. ive tried on many different browsers too, they dont seem to work either, but it started on opera. if anyone could try to give me some solutions, id be genuinely happy, thanks 
(ive used edge, chrome, opera, and opera gx and none of them download stuff, if that helps w anything)
