pyRevit 5 + Revit 2025 + Cpython3

Hello
I am reaching out to you with an issue regarding the latest release of pyRevit 5.0 in combination with Revit 2025 and CPython3. In Revit 2025, I converted all the nodes in Dynamo from IronPython2.7 to CPython, as Revit 2025 requires it, and everything works fine. However, when I install pyRevit 5.0, none of the nodes in my script, which is written in CPython3, work. The errors reported are varied, but most often it says “built-in function import returned a result with an error set.” As soon as I convert the nodes back to IronPython2.7, they don’t work either, but they don’t work even without pyRevit installed. Could someone help with this issue? Thanks

The same error is in 4.8 also, there is an Issue on it in Github.

@Jonn.O Thanks for your reply, seams it does not have solution yet.
