With Chrome upgrade to Version 73.0.3683.86, Dynamics CRM both Online and On-premise are having an issue with loading form and stuck at Loading Business Logic.
This happens only when a record is opened from related entity associated view or from sub-grid. No issues when navigated directly to open form from navigation menu or advance find.
Please note that this issue is only with Chrome and not with IE and also converting to TurboForm is not an option for us.
When I looked at the console, there were some javascript errors related to Mscrm.TurboForm.Control.CustomScriptsManager.frameElement.contentWindow.... is not a function
