Sorry to hear about your experience. I'd recommend resetting preferences of Adobe InDesign manually. Please follow instructions to do that below:
Close all adobe applications
Go to Locations:
Rename Adobe InDesign and com.adobe.indesign to Adobe InDesign.old and com.adobe.indesign.old
Launch InDesign from the CC
**Please note that resetting preferences will remove all the custom settings and InDesign will launch with default settings. This way all your old settings will be saved in .old folders and InDesign will recreate new folders with default settings.
If that doesn't help, try booting the system into Safe Mode (https://helpx.adobe.com/in/x-productkb/global/start-safe-boot-mode-mac.html) and check how it works there. It starts your system so that it performs certain checks and prevents third party software/ services from automatically loading or opening. If it works fine in Safe mode, then there is some third party service or application like antivirus, plugins or web extensions which are conflicting with the InDesign
