Unreal Engine 5.5.1 Bug

Developers of the Unreal Engine 5
I recently came across a problem that is the ai perception is broken.
Everything works perfectly for me on version 5.4.4, but when I updated the engine, I noticed that for some reason aI stopped forgetting enemies. After the debug, I realized that the problem was with ai perception. If this is not the case, then I will be glad to know the reason and a way to solve this problem.
All the best

changed: if the enemy starts moving, the AI understands that the enemy is not in him field of sight.
