RTC crash (2017 CU20)

otk17

RTC crashes sometimes when I navigate between Outlook and RTC and try to copy some text in Outlook. The user doesn't have any personalization. Another users dont have this problem. .Net Framework is 4.7 as on another machines.

I get follow in event log.

Application: Microsoft.Dynamics.Nav.Client.exe
Framework Version: v4.0.30319
