Canon Rebel T7/Sigma 150-600 - Lens detaches itself

Hello - I am using a Sigma 150-600 Contemporary lens that seems to "unscrew" itself from the camera body mount periodically. The lens fell twice and I sent it to Sigma to get checked out. They replaced the mount but it happened a couple of times since then (luckily the lens did not fall). I am typically shooting birds, so I do zoom in/out frequently.

Has anyone had this happen? Is there a problem with the camera body or am I just "carrying/using it wrong"? I typically have it slung across my body, lens facing down. I am using a Peak Design Slide strap with one anchor on the camera body (top left) and one on the lens mount.

Any tips or solutions would be appreciated. Thanks!
