Cant build my game anymore. I think it has to do something with the UnrealDrive plugin.

And I also uninstaled this plugin, but its the same error.

Hey there @Croffe! So from the log it looks like it’s looking for a UD preset data type when cooking, causing it to fail. The first thing I think we should try is checking if the ini files have their entries for this removed and all cached data from the time the plugin was installed is gone.

First, back your entire project up somewhere safe.

Then, can you search your Config/DefaultGame.ini file for UnrealDrive and delete the lines that reference it.

Then, can you go to your project directory and delete the Saved, DerivedDataCache, and Intermediate folders. All of these (with the exception of builds) will be regenerated on next launch. (You may be able to ignore DDC but I always recommend a clean rebuild of these after big changes anyway).

Check your uProject file to see if the plugin is listed as a dependency, if so remove it entirely or flag it as false.

Then relaunch your project to rebuild those caches, then attempt a clean build. If anything new breaks, then you still have your backup to revert to to try other things.

Let me know how this goes!
