Oracle s3 sync on ipad crashed the app

Operating system

iOS

Joplin version

13.0.7

Sync target

S3

What issue do you have?

I switched sync target from dropbox to oracle s3, and the app crashed. So crashed that I can not enter the app anymore. I tried redownloading the app again, but once I set up the s3 profile and hit synchronize, the app crashed.

ios (I used an ipad and do not own an iphone) is the only platform this happened.
