right click with any mod item teleports you underground

Issue:

Right-clicking with any mod item in hand (weapon, item, block) teleports you instantly underground to a specific location. The location varies in each world but is in the realm of -5.3, 0, 5.3. 

Problem started after:

This workspace is the immediate result of four merged workspaces. None of the workspaces had this problem before the merge. I'm not getting any errors, however.

Steps I've taken to try and fix:

<your user home folder>/.mcreator/gradle

In this folder, there is a folder called caches. Delete this folder and open MCreator again. Next build will take a bit longer as caches need to be rebuilt. If you can not delete all files in this folder (which is necessary), reboot the computer first to remove any potential file locks.

If this is not enough to make things work, delete the entire gradle folder, not just caches, and try again.

If even this fails, try to delete the entire <your user home folder>/.mcreator/gradle folder, create a new workspace with the same generator version as the version of the workspace failing, after the setup of this new workspace is done, open your current workspace, and click Build & run -> Build workspace, then Build & run -> Reload gradle project and then Build & run -> Regenerate code and build.

Context:

Using forge 1.18.2

I exported the mod in case anyone is interested: link

Any help/suggestions would be much appreciated. Thank you in advance!
