Can you please confirm if the issue is happening for only 1 user or multiple users in your environment?
Also, I see that you have already tried reinstallation, but did you delete the remnant files manually?
Can you perform a uninstall one more time, then follow the steps below to clean up the environment of any remnants, try the install again and the crashing issue should be resolved.
Delete the below mentioned Registry Keys
HKEY_CURRENT_USER\Software\Microsoft\MSCRMClient
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSCRM
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSCRM_Setup
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSCRMClient
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\MSCRM
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\MSCRM_Setup
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\MSCRMClient
Delete the MSCRM Folder from "C:\Users\<Logged_in_User>\AppData\Roaming\Microsoft" and "C:\Users\chiragbh\AppData\Local\Microsoft".
Delete the installation Directory for MSCRM outlook client, by default it is "C:\Program Files (x86)\Microsoft Dynamics CRM" on a 32 bit computer and "C:\Program Files\Microsoft Dynamics CRM" on a 64 bit computer.
