Lightburn won’t start

The first test after a long absence is to sign into Microsoft OneDrive and restart LightBurn to see if the issue resolves. I’ve seen it one other time here.
If it doesn’t resolve and you have the installer handy, without even deleting the Current Version of LightBurn, please Right click the installer and select ‘Run as Administrator’ and turn it loose with all the authority.
Please ensure you’re not using Cloud, Shared or external storage for LightBurn or your LightBurn files. Some systems are showing that the shared storage loses data and it’s still being worked on.
Either way, Please let us know what it was.
