specific drawing keeps crashing

I have a specific file that keeps crashing and I can hardly edit it before it aborts.  It seems I can draw a line or two and then about the third item I try to add or modify LibreCad crashes altogether.  Sometimes if the first thing I try to do after opening the file is trim or copy it crashes right away. The problem seems to be file specific because I have dozens of other files I've created over the years, some of which have many layers and are rather large in size, and I can work with these files all day long without any problem. Is there a way to repair corrupt files?  I'm working on Windows 365 and my LibreCad version is 2.2.0 compiled Jun 12 2020.  Any help is greatly appreciated.

I can echo this. It was working fine on a fairly small file, although set for large output(A0). Nearing end of one block, it came up Not Responding and when I restarted I noticed that the autosave had prefixed my file name with a #. I am using Windows 10 and LibreCAD v2.2.0, the same as Rusty.
