VirtualQuery Error (vtable constructor failed: virtualtablename) in UniDAC 7.0.1

Product: Universal Data Access Components Product Version: 7.0.1 OS Version: Windows 10
Platform: x32
RAD STUDIO C++ 10.2 Tokyo version.

This error: vtable constructor failed: virtualtablename occurs with VirtualQuery component in design mode.

and this one : Project xxxxxx raised exception class ESQLiteError with message 'near "(": suntax error'.
in runtime mode.

I'm using VirtualQuery to read a VirtualTable's records.

The provider is MySQLUniProvider

The same project in Berlin U2 with the previous UniDAC components version works perfectly.

thanks
Giovanni
