virus on my iPad?

I’m not really sure what’s wrong on my iPad but most of the iPad’s functions not work as intended as I’m frightened that it may has a virus…

as such I can’t access to YouTube and safari detects every secure as “connection is not secure” after getting an error message “Cannot verify server identity” of something related to “the identity of ‘eventshower.com’ cannot be verified.”

my iPad is updated to the latest version (16.6 security update) and I don’t know how to fix this issue, any suggestions?
