Ah, sorry, it’s working now. Somehow I downloaded 1.8 version instead of 1.8.1. Sorry for complaint
"Couldn't parse iCalendar object" error message

I do know that this is a bug from Apple. But unfortunately, I cannot resolve it by emailing them or whatever (it was not my decision to go with a big SV company).
Upon parsing the next line of X-APPLE-STRUCTURED-LOCATION
Error at line 3,736: Expected , read 
“t\n10116 Offenbach am Main”
Somehow thunderbird display this event properly (but my thunderbird is read-only).
Inside apple-calendar (both desktop app and WWW) this event does NOT exist. Otherwise I would delete it.
Is there any workaround (other than me deleting this calendar)?
Thanks for supporting open source!

If thunderbird displays the above event try to delete that event there and trigger a sync. Otherwise - if you don’t have real access to your data on a file basis - you can export the calendar into a file, delete that event manually in a text editor and import the data again ino a new calendar.
Hm, I guess the problem is the unescaped
X-APPLE-STRUCTURED-LOCATIONline. I don’t think there is an easy way to work around that. Creating a new calendar without that event like suggested by @devvv4ever is probably the best solution.
