TAdvStringGrid ColumnHeaders Access Violation

When we try to access grd->ColumnHeaders->GetText(), we're getting an access violation:

Project Project2.exe raised exception class $C0000005 with message 'access
violation at 0x6de4928f: read of address 0x00000018'.

I compiled and run this here and click "Button1" but I cannot see an error here.
I can only assume there must be something corrupt in your IDE setup.

Thanks Bruno.

I did an install of RAD Studio 12.1 in a new VM. then installed VCL UI Pack and encountered no issues. That also fixed the other issue I reported with adding rows to the AdvStringGrid.
