It appears to be a plugin library from another LibreCAD installation.
If so, uninstall all other versions.
If in doubt, you may simply remove that file.

Each time I open LibreCAD lately I get a prompt that says:
The plugin‘C:/ProgramFiles/LibreCAD/resources/plugins/pointstocsv1.dll’ uses incompatible Qt library. (5.15.0) {release}
Does this mean anything? I'm using windows ten with LibreCAD 2.2.0.2 Qt version 5.12.11
Thank you
