Revit 2021.1.5 crashes when clicking on "export ifc" button

[MOATTI_RIVIERE]

Hello there,

I'm having a very annoying issue for wich I don't find any solution...

When I want to export my model in IFC, Revit crashes when I click on the IFC export button, closing without any warning.

What I already tried:

- reinstall revit, install hotfixes, reinstall ifc exporter 2021

- exporting a 1 wall project : same result

- using only one screen (saw this on another post)

- exporting my model with another PC worked

I'm stuck here. If anyone have an idea about what's happening, i'll be glad to hear

Can you use the built in IFC exporter instead of the add-on?

Hi,

Sorry for the late answer, I've been away from work for some weeks.

Neither the add-on nor the built-in is working. Exact same crash result...

It seems to be a weird bugg, I still can't find any post or article with the same isue
