Load error

[jolly wharf]

firstly missing dependencies, secondly no null handeling

or the null error is because it failed to load the library

System.Drawing https://nuget.info/packages/System.Drawing.Common/7.0.0-preview.4.22229.4 -> lib -> net462

(should be it)

for the mysql he has to use the one he used when making it

[jolly wharf]

he doesnt

that error wouldnt be thrown if he had it

[frail rock]

Then he has the wrong version

[jolly wharf]

Well why didnt he send him the version he used when buidling the plugin

[ocean heron]

use the one in the unity installation

C:\Program Files\Unity\Hub\Editor\2021.3.29f1\Editor\Data\MonoBleedingEdge\lib\mono\4.5\System.Drawing.dll if you installed it through unity hub
