Could you try to find out which mod is causing this issue with LittleTiles? I suspect it is "IVToolkit", because its the only other coremod. So you would really help me by testing it out.

Removed IVtoolkit but same crash happened. Place the hammered block, player moved, then freeze or crash.

Fixed particle issue, could you try out the newest CreativeCore version and check if it still happens?

New version works well, thanks for fixing.

Nice thanks for reporting this issue. Wish you a lot of fun playing with my mod.
