Description

Regression: Tested in //UE5/Release-5.0, this issue does not occur so regression is yes.

The GPU Timeout only occurs in UE5/Release-5.1, as recreating this issue in previous versions of the editor does not result in any freezing or GPU Timeouts. 

Warning Message: 

Warning: GPU timeout: A payload (0x00000A6586AFDBA0) on the [0x00000A656D2E2280, 3D] queue has not completed after 5.338463 seconds.
Steps to Reproduce
  1. Create a new Blank BP Project with the Water Plugin enabled
  2. Create a new Empty Level
  3. Add a Directional Light to the level
  4. Create a Landscape and set the Section Size to 255x255 Quads and Overall Resolution to 4336x4336
  5. Add a Water Body Ocean to the level
  6. Observe the logs

Actual Result: Editor starts freezing and logs start warning of a GPU Timeout

Expected Result: No GPU Timeout occurs and the Editor does not start freezing
