I have this problem where Revit 2020 and 2022 stared crashing when exporting to IFC. I would have never conected this to Enscape but i found this thread about someone having the same problem and mentioning Enscape, so I uninstalled Enscape to test it. IFC export works. Hope you have a fix for this some time soon.
Elvir , we're aware of this behavior and this issue will be resolved with our next upcoming preview (8) soon - If you do not want to make use of the preview version, then you may also wait a bit further for our official 3.3. release which will be around the middle of April.
I'm sorry about this current inconvenience.
