Hope you weren’t injured Dilalio!
Oh goodness
yes, you need to vent the waste upstream of the slug of water exiting into the main run, an antivac trap will do that. Just remember to clean it periodically. You do get anti vac bath traps but you need to have the clearance as the valve sits on top of the outlet section.Just one more thing. If the gurgling is coming from the bath when the basin empties, should an anti syphon trap (AST) be fitted to the basin to stop that or is there an anti syphon for bath waste ? I guess there’s not much room for a bath AST.
There’s a soil stack running internally to the right of the toilet and I believe this vents out through the roof.

The reason for the water entering the bath waste is due to the water always following the path of least resistance.
This can be down to a few things - still a restriction downstream of the where the basin connects to the mains waste, so the initial water surge travels upstream - the fall of the waste run isn't enough to ensure the initial outflow all heads downstream - The waste would ideally increase to 50mm at the branch of the basin waste if the fall isn't suitable.
Apologies D, isn't it really feckin frustrating when in the middle of elaborate explanation of things the 'there are more posts to display' message pops up and then realising that someone has got in there first.You posted that while I was still trying to write
