Fyi, same issue here (for the record).
GNS 530 V2
GNS430 V2
However, I already rolled back as I need to use them for practice. Just wanted you to know this is a wide spread issue. Note I only use my computer for sim and it's fairly new. It appears this is a sure issue for anyone who upgrades to Windows 11.
I'm XP11.
