I updated to SDK 3.8.1 this week and last night tried to open a small unity project that was build with 3.7. It crashes directly after opening and since the SDK upgrade was the only real change on my system I assume those two things are connected. Is it somehow possible to update the ZED plugin within the unity project without opening and crashing it to try if that fixes my issue?
As I guessed, the Unity plugin version has to be the same as the SDK version. So, if you upgrade the SDK to 3.8, you have to do the same for the Unity plugin.
