.Json files download incorrectly after updating to iOS 26

I’ve been using Perchance recently, but whenever I try to save progress, the .json file downloads incorrectly. I tested to see if it was my phone or Safari and Chrome does not have this problem, but I cannot use Chrome. Files download as .json.download, which will not load into the website, so I tried deleting “.download,” which did not work. I try to open the file and it comes up blank. I tested and images do not have this issue either. Settings>Safari>Downloads and changing iCloud Drive to On My iPhone did not work. Restarting my phone did not work. I did not have this issue prior to downloading iOS 26.
