Hi @Lord and @Catalys
I also had problem on 2.2-0.rc-2 .dmg on my MacBook Pro i7, Big Sur 11.1.
Application start hanging and does not start.
Same problem on 2.2.0.rc-1
No problem, with vers 2.1.3.
I compiled source code from from 2.2.0-rc.2
https://librecad.readthedocs.io/en/latest/appx/build.htmlAnd the LibreCad.app compiled is working.
Let me know if I can share it or do you need other info.
Thanks
