Most probably not since doing that means supporting WPF in cpython. I haven’t seen any libraries for that. I’m hoping IronPython 3 would show up before that
Ehsan, yes, I am having issues with pyRevit not working in 2020/2021 which is why i asked if it others are having that issue. I did have 4.8.11 installed prior to the availability of 4.8.12 and both were installed after installing 4.8.12.
You could check what revit plugins are installed for 2020/2021 and not installed for other versions.
It may be a dll conflict or the loading sequence of revit bypassing the pyRevit loader @SH-MEP_BM
A clean uninstall/ pyrevit doctor command /install might fix it.
