ISY not found and opening Iced Tea ever since upgrading to windows 11

[Blackbird]

Isy finder cant find the ISY and when I try to open it it opens in iced Tea.  If I open with JAVA web launcher the same thing.  I can access the ISY through the portal.

I rebooted my pc and now I see the ISY.  Not sure why that made a difference.
