I'm trying to run the new Gaea nodes [youtu.be] in Houdini, but I'm getting this error on any node I try:

Invalid source /obj/box1/canyon1/error_report/attribvop1.
(Error: Gaea 2.0 cannot be found on your system. Please ensure it has been installed for this plugin to work. To install Gaea, look at the Help for this node.).

Houdini Indie version: 20.5.278
Labs version: 20.5.410
Gaea 2 Professional version: 2.0.5.4

Has anyone else run into this? I would really appreciate any help because these nodes look fantastic and I'd love to try them out.

I'm not sure why this worked, but I'm happy to have things working now! For anyone in the future that runs into this, I did a full uninstall of Gaea, restarted my machine, and installed the exact same Gaea version again.

I am experiencing the same issue.
Houdini 21.0.440
Labs 21.0.553
Gaea 2.2.6.0

The re-install and re-start did not work so far

Tested also with
Houdini 21.0.553
Labs 21.0.553
Gaea 2.2.6.0

Same error
