Revit crash on Assistant launch

[MohamedAsli]

Revit simply crashes when attempting to launch the Assistant.

To Reproduce

1. New okpy file
2. Click on '🤖Assistant'
3. "An unrecoverable error has occurred. The program will now be terminated..."

[MostafaElAyoubi]

Hey there @MohamedAsli !
Super excited you're already giving the assistant a shot! :)
In which version of Revit are you experiencing this issue?

[MohamedAsli]

Hi @MostafaElAyoubi
Sorry for the lack of info

Revit 2020.2.9
20220517_1515(x64)

[MostafaElAyoubi]

Thanks for the info! We're having à hard time reproducing the issue on our end. Could you please see if you get the same crash on another version of Revit?

[MohamedAsli]

I've tried on 2021 and 2022.1.3, got the same problem.
Here's a snippet where we see the raised exception from my journal file on 2022, I don't know if it helps
I've disabled all my plugins, only Orkestra and Okpy left

Hi @MostafaElAyoubi

I am encountering the same behavior on Revit 2022.1. If I can further assist with information about this, let me know.

[MostafaElAyoubi]

Thank you very much for the précisions. Could you please share the list of addins you have installed ? This could be a conflict with resources loaded by other revit addins but we're not sure yet.

[adriangrosu2907]

On my end, I do not have any other add-ins installed so far, the first to install was Orksestra :) after a clean install of Revit.

[MostafaElAyoubi]

I love your priorities @adriangrosu2907 😄 !! Which version of windows are you on?

[MohamedAsli]

For Revit 2022 I've disabled all non-autodesk plugins.
I made another test on a brand new installation of revit 2024, same bug :/
No other addins except the Autodesk ones ⬇

[MostafaElAyoubi]

This is super helpful thank you very much🙏

[MostafaElAyoubi]

can you please try re-downloading the installer and re-installing?

[pkitchenks]

I'm having a similar issue even after downloading the updated installer. Revit 2024 with no additional add-ins installed.

[MohamedAsli]

Uninstalled and reinstalled.
A good step forward, now the assisant window opens fine.

The first test revit crashed just after my first prompt

The second test, it crashed after the second prompt

[LeeFried]

I decided to give this a shot. I uninstalled v1.6.1 and performed a clean install of v1.7.1, with no change to my Revit installations.
If I open OkPy, create a tool, then click “Assistant”, it crashes Revit. It crashes all versions from 2021-2024.
We don’t have the luxury of reinstalling Revit on every user’s computer to remedy this.

[MostafaElAyoubi]

Thanks for reporting @LeeFried .
Réinstalling orkestra only seemed to work for some people. It is inconsistent though. We're still investigating.

[MostafaElAyoubi]

@MohamedAsli it is à step forward for sûre. We're probably going to share à débug installer to try and track down and fix this . I'll reach out soon.

[MostafaElAyoubi]

Fixed in 1.7.2
