Tool experienced an error

I’m trying to get into a design I worked on a few days ago and get that the “tool experienced an error” in an endless loop. Help?!

Hi,
could you provide the design id?
Thanks

It seems to be OK today. It was a design that was imported and there were parts being created, so maybe it was something with that? I am a bit nervous, so will likely be restarting the design in another ‘file’.

For the future: How/where do I find the design ID?

The design id can be extracted from the project page URL
