I am stuck in insbruck - no calendar and a few list riders. 2nd time this had happened and tried a new install
Try renaming your prefs.xml file to prefs.bak and run Zwift again.
It’s the configuration file, maybe something is wrong with it. The prefs.xml file also has the WORLD setting in it, which for some reason might be “stuck” for you.
Do report back if it helps.
