Lost all calendar events on iPhone after iOS 18.5 update

I Updated my iPhone to 18.5 and my calendar events are completely gone. I have tried everything and contacted Apple multiple times. Right now, I am currently using an old device to see if I can use an older iCloud backup to get the events back. I tried one backup, and it didn’t work, so I am working on another older backup to see if that will work. If not, then I have no other options. There was no restore backup on iCloud.com for the calendar either; it seemed to have deleted as well. There was definitely a glitch in their recent update, as I have checked on Reddit, and Apple said a lot of users are contacting them about this. I use my calendar for everything, and it’s all gone.

The Apple update 18.5 deleted the “In my phone” iCloud calendar completely the only events that were still there were my email calendar events. The restore on iCloud.com was also deleted. I haven’t had any issues with my calendar until this update it deleted 3 years worth of events.

I used an old iPhone device I had and downloaded an older version of my saved iCloud backup at setup from 6-12-25 which was before the update and I successfully got the calendar events back up. I then had to go through every single day and save each event to my email calendar instead of iCloud so now I have all my events on my current device.
