I had exactly the same thing happen today trying to open the programme! (not in an open drawing like flywire)

I then tried to open the .dxf~ file (renaming it and removing the '~') but the same thing happened.

I'm not a techy so would be really grateful if someone could help with this.

And I really don't know what I was specifically doing before this happened except to say I just closeed down an open drawing and exited the programme in the normal way, which seemed fine at the time.

Many thanks

OK.... false alarm! Must have unwittingly corrupted the programme somehow.

I uninstalled LibreCAD and reinstalled using my original installer file and the drawing opens alright now.

Phew! That was close! Hope that works for you too flywire.

That particular assertion has been removed from both development, i.e. 2.2.2-alpha, and the 2.2.1 branch (should be in 2.2.1.2).

Hatching may fail, but it should not crash the whole app.
