Could it be that the range is defective.

I need to get inside the objects to build or dismantle it.

Hmm, can you provide your save game?

It looks like your character is set to collide with the drones, maybe some other mod is affecting the drones

Of course I will upload the mod folder and the savegame.
Mod folder is important, some things were translated into my language.

What I also noticed is that the game crashes when you remove a lot of things that have long underground belts or items in the loader, then they are not removed and the drones stand around.

I found out it's that mod. Walls Block Spitters. https://mods.factorio.com/mod/walls-block-spitters
When I turn it off the drones run normally I turn it on I have to get inside the object to build them.
I hope there's something you can do.

Wanted to say that with version 0.6.2 everything works fine, no more range problems.

Thanks for the great work.
