I was looking for a solution to the same problem.
I don’t remember if this had happened since the first install.
However, it was not fixed even after uninstalling all versions of vvvv.
I solved it in the following way.
vvvv_beta_39_x64/lib/nodes/nodelist.xml
edit and delete from line 4955 <NODE factory=“VVVV.Hosting.Factories.DotNetPluginFactory”…
to 24154 </NODE>
The cause is probably this sentence included.
filename="…\…\…\…\…\…\…\…\Users\buildserver\AppData\Local\vvvv\beta_x64\packs\dx11…
