      Has anyone seen something like this before, and might know what would be the cause?

        Some things to check.

        Does it work in any other DAW? Reaper for example.
        Does it work standalone?

        Sometimes different DAWs give you better debug output.

          .exe will not open at all, nothing happens.
          It does not show up in Reaper. :astonished_face:

            @Lindon wasn‘t there something that caused your plugin to crash when using the copy protection flags?

              Did you use any scriptnode? If you left any network at Allow Compilation and exported that way, it results in a broken plugin that doesn't load.

                I did mess around with a stereo effect at some point. But removed it again. How can i see if there is anything leftover?

                  Could this be the cause of it?

                    I painstakingly spent the whole night, copying my project and removing code and UI elements one by one, and exporting every time i did a change. I added +1 to every version to make sure if was a "new" vst3 export that i could test in my DAW.

                    It only worked when i deleted absolutely everything except a background image.
                    BUT, one time i deleted "Sampler1" and it worked while still having some code and UI elements. I tried again, because it seemed weird, but it only happened once.

                    I'm at a loss.
                    Something is messed up beyond recognition.

                      @ThinkTank You can try to remove the line in your code. Make sure to always clean the build folder for a clean build.

                        if there was I cant for the life of me recall what it was... sorry. I never use copy protection flags - unless Im misunderstanding this...

                          @ThinkTank -- ok I looked thru the old topics - and found the one Christoph was referring to I think... I also think you may have found it too, but just in case:##try removing your Presets code... dont load a preset on start up, and make sure that FL Studio is using fixed buffer sizes...

                            For some odd reason it worked to remove preset codes and browser, and then just undo and export again. I have no idea why. But im just happy it works.

                            Thanks guys
