Dynamo Player Stuck on Loading

Dynamo Player
1

Hi,

I’m having a problem with dynamo player

I’m using revit 2026 and in the past months i don’t have issue running dynamo player, but right now i cant use dynamo player, when i click it, it opens then gets stuck on loading, i tried waiting for 5mins but it doesn’t work, and when i try to close it and reopen dynamo player, the icon is grayed out

I already tried uninstalling then reinstalling, and also the dynamo player cache delete tutorial

I’m out of option and ideas on how to fix this.

Can anyone help? Thank you

Same issue here. The only thing that changed is I installed the latest windows update. Yesterday it was working fine. The loading does dump onto the sample screen but cannot load any of the default folder paths. It also will not allow me to click yes or no to the trusted folder path.

I also tried the fixes outlined in this article but nothing has worked. Dynamo Player button is grayed out or the dialog box does not appear in Revit

I have tested 2024 and there is no issue. The problem seems to be R25 & R26 so a Dynamo 3.3+ problem.
