Delphi bug: Exception EAccessViolation in module rtl210.bpl at 00016A9C [SOLVED]

I keep getting this error at Delphi shut down:

Application Error – Exception EAccessViolation in module rtl210.bpl at 00016A9C.
Access violation at address 50066A9C in module ‘rtl210.bpl’. Read of address 06152AF8.

Solution 1:

The problem is fixed by restoring this registry key to its original state: [HKEY_CURRENT_USERSoftwareEmbarcaderoBDS15.0Known IDE Packages]

Here is the pristine value for this key:

[UPDATE]
SOLUTION 2 (and cause):

After some work I discovered what caused this: The ‘FMX controls’ package was disabled (probably I disabled it since FMX is still infantile and I don’t intend to use it right now). Re-enabling this package solved the problem.

Also removing “$(BDS)\Bin\delphiwin32210.bpl”=”Delphi Win32 Platform” helped.
