[CodeLab v6.12 for Paint.NET 5.0.12 (Updated February 11, 2024)]

Receiving this error:

File: C:\Program Files\paint.net\Effects\CodeLab.dll

FinalUpdate: Looks like StewienFilters.dll was the culprit, CodeLab opened with every other plugin except this one.

[Icon, Cursor, and Animated Cursor Format v3.7 (May 2010)]

Used to be able to open and save ico files, but now I get this:

System.MissingMethodException: Method not found: 'Void PaintDotNet.Surface.SuperSamplingFitSurface(PaintDotNet.Surface)'.

Using
paint.net 4.0.3
IcoCur.dll 3.7.0.0

Update 1: After removing all Effects from the folder, I can now save as a .ico... Looks like I'll be hunting down which one is the culprit since the program doesn't show any failed plugins in the settings.
Final Update: Well that's embarrassing... Some of the .dll's that were in the FileTypes were also in the Effect folder. After removing those, everything works fine... Don't make my mistake !!!
