Do you still get the error if you remove the loop in the wall?

And if you correct the orientation of the line wall in the top right corner (it’s yellow tick mark points out, not in)?

Nice questions. I don't seem to be able to remove the loop in Therion. Can you?

I will try to do it in Topodroid.

Thanks,

Rodrigo
