Mac preview release fails to load extensions in the Extension Manager

[DeepaKrishnaswamy]

Hi,

I installed the latest Slicer Preview Release 2026-03-29 (Slicer 5.11.0 revision 34472) on Mac. I noticed that the extensions are not loading in the Extensions Manager:

I checked cdash and noticed many errors, even for extensions that should work like SlicerRT.

Thanks!

Thanks for reporting.

Yes, it looks like pretty much everything is failing on the preview, while the stable look more normal.

@pieper

it looks like pretty much everything is failing on the preview

AND it seems that pretty much everything has been failing since March 22!

@Sunderlandkyl this can’t be related to the Girder work you’ve been doing, right?…
