Elementor refugee

Elementor has managed to mess my site up as their licensing system made my pages screw up when their website went down!!
I also can’t have a staging site without doing it on a local machine on a single license.
No subdomains or anything.

So that’s my question, can I have a staging site with Beaver (subdomain or folder) on the single license.
Will my site pages go screwy if Beaver has problems with their system?

Thanks in advance!
