Edit instrument empty VST window PLAY

Hello eveyone I hope someone can help me. I reinstalled Nuendo 4 on a windows 10 laptop, then I installed some libraries and VST instruments I used before in a Windows 7 laptop.

The problem is when trying to load and edit the PLAY VST instrument, it shows as an option and “loads” correctly but when I click in the Edit Instrument button I just get an empty blank window but the instrument is not showing (see picture attached). I have other 2 VST instruments and they load correctly and show properly in the edit instrument window but specifically the PLAY VST instrument is not showing at all.

Things I have tried:

  • Reinstall Play 4 and Play 6 separately with the 32 and 64 bits plugins
  • Change the program DPI individually because I have a 4K monitor
  • Tried in a different monitor
  • Tried opening the program in compatibility mode for Windows 7, 8 and XP
