Fatal Error on Account Entity after click the "publish all customizations"

Recently, we invited a vendor to work on an upgrade project from Dynamics CRM 2015 to Dynamics 365 on premises.

we are using "Migrate by using a new instance of SQL Server", which we setup a different network and environment for dynamics 365. we are still in progress of doing the upgrade, however there is a hiccup generated in our previous Dynamics CRM 2015 development environment. 

it is found that after click on the "Publish all customizations" button under "Settings" > "Solution". 

When I click on any of accounts, it will shows this..

is there anyone can point me a direct to trace this issue? 

To revive this error, I must be doing this on database rollback, but I cannot update the customization to the environment. please help! please!
