Which pyRevit version? Would you mind running pyrevit env on command prompt and sharing results?

I'm also receiving similar errors, just installed pyRevit v4.8.12.22247 Here is results from pyrevit env: ==> Registered Clones (full git repos) ==> Registered Clones (deployed from archive/image) master | Deploy: "basepublic" | Branch: "master" | Version: "4.8.12.22247+0031" | Path: "C:\Users\econcolino\AppData\Roaming\pyRevit-Master" ==> Attachments master | Product: "Autodesk Revit 2023" | Engine: IPY277 (277) | Path: "C:\Users\me\AppData\Roaming\pyRevit-Master" master | Product: "Autodesk Revit 2022" | Engine: IPY277 (277) | Path: "C:\Users\me\AppData\Roaming\pyRevit-Master" master | Product: "Autodesk Revit 2021" | Engine: IPY277 (277) | Path: "C:\Users\me\AppData\Roaming\pyRevit-Master" master | Product: "Autodesk Revit 2020" | Engine: IPY277 (277) | Path: "C:\Users\me\AppData\Roaming\pyRevit-Master" master | Product: "2019.2.6" | Engine: IPY277 (277) | Path: "C:\Users\me\AppData\Roaming\pyRevit-Master" master | Product: "2018.3.3 Security Fix" | Engine: IPY277 (277) | Path: "C:\Users\me\AppData\Roaming\pyRevit-Master" ==> Installed Extensions ==> Default Extension Search Path C:\Users\econcolino\AppData\Roaming\pyRevit\Extensions ==> Extension Search Paths ==> Extension Sources - Default https://github.com/eirannejad/pyRevit/raw/master/extensions/extensions.json ==> Extension Sources - Additional ==> Installed Revits Autodesk Revit 2023 | Version: 23.0.20.21 | Build: 20220726_1500(x64) | Language: 1033 | Path: "C:\Program Files\Autodesk\Revit 2023" Autodesk Revit 2022 | Version: 22.1.30.34 | Build: 20220520_1515(x64) | Language: 1033 | Path: "C:\Program Files\Autodesk\Revit 2022" Autodesk Revit 2021 | Version: 21.1.70.21 | Build: 20220517_1515(x64) | Language: 1033 | Path: "C:\Program Files\Autodesk\Revit 2021" Autodesk Revit 2020 | Version: 20.2.90.12 | Build: 20220517_1515(x64) | Language: 1033 | Path: "C:\Program Files\Autodesk\Revit 2020" 2019.2.6 | Version: 19.2.60.3 | Build: 20220224_1700(x64) | Language: 1033 | Path: "C:\Program Files\Autodesk\Revit 2019" 2018.3.3 Security Fix | Version: 18.3.3.18 | Build: 20190510_1515(x64) | Language: 1033 | Path: "C:\Program Files\Autodesk\Revit 2018" ==> Running Revit Instances Error: Object reference not set to an instance of an object.

Hi

I was getting similar error and the reason it was happening for me was I had not uninstalled previous version of Pyrevit (4.8.8). I had both versions installed. I had to uninstall both versions and install fresh copy of latest version of Pyrevit for it to work . Hope that helps

Thanks a lot . it is working
