You're the only one to report me this problem, I just tried and it worked for me, you can send screenshots in the discord server if the issue persists.

You can only build with the ant you summoned with the 2nd ability, tap the down key to stay still.

which is the discord server

I'm also reporting that formian's ants don't mine some blocks for whatever reason and it's definitely not hammered block problem. They just straight up ignore some of them. For example randomly select ~4 blocks of stone or a single block of dirt etc. I'm making a hellevator at the time of writing and they leave some blocks which are perfectly mines manually.
Also they tend to ignore blocks that are near you (about 1-13 blocks) from you which is also weird.
if you want screenshot-proofs, i can provide them as well.
