After adding fuel to the mining drill/buzzsaw and attaching the drillhead/saw onto the tool, I tried to use it on a block of dirt. Once I did that, however, the game would crash and the launcher would output the following error: "java.lang.IllegalStateException: Already building!". Afterwards, I would no longer be able to load into the world that just crashed, as the game would just crash again without me even entering the world once it was 100% loaded and would output the same error.

I had other mods installed, so I tried to remove those mods and try again, but the issue still persists. The crash report below is when I only had the Immersive Engineering mod in the mods folder

Sorry, just saw that there was a previous post about this in the "closed" issues
