Backwater Swamp - Red Glyph Trap
It's possible for a Red Glyph on Backwater Swamp to spawn in a location that causes you to get stuck in the ground when interacting with it.
There was no way for anyone to help me, and after the killer downed me I fell under the boards and became even more trapped, being forced to bleed out.

I also got one on the same map but in a different spot, it was just too high in the air for me to get it
