If you are starting Lychee Slicer and have noticed that your 3D printer list and resin settings are missing, please be assured that your data are not lost.

This problem happened to some users after we performed a database migration to a new system. We are working on fixing the issue and resolving the problem for these users, and we are sorry that you are facing this issue.
