IW 15.0.21 vs RAD C++ 10.2 update 3

[duffo64]

Sirs,

After 15.0.21 installation, as soon as I recompile an existing project (or create and run a new empty one) it fails:

Exception message : Error reading IWForm1.Width: Access violation at address 00B91998 in module 'Intraweb_15_D10_2.bpl'. Read of address 00000008
Exception class : EReadError

P.S.: trying an empty project with RAD C++ 10.3 update 1 works as expected

What happened ?_?
