Opening saved level gets stuck on 100% "performing post-load"

Development Pipeline & Plugins

Exported a large Revit model using datasmith.
First time import, although it took quite a long time, came into Unreal without issue. We could navigate around the level with no issues.
Saved the level and exited Unreal.
Came back and tried to reload the level and having tried several times to do this it just gets stuck on 100% “Performing Post-load…”.
Eventually, after 10-20 mins, it defaults to the standard blank scene.
Anyone know why this might be happening?

Many thanks in advance.

Hi Jason.

If you’d be willing to share the source file, or another test case that also reproduces the issue, this seems like a potential bug report that our team would like to investigate further. Please submit a bug report at the link below.

I know it’s something you’ve definitely checked, but is not it that opens up the standard level while your project is saved on another level?
