Notes:
- Does not reproduce in the editor
- Does not reproduce if the URP configuration assets are deleted/recreated
- The app crashes due to running out of memory based on logcat logs ({{The process has exhausted 256M for size class 65552}}, {{libc++abi terminating due to uncaught exception of type std::bad_alloc: std::bad_alloc}})
- Could not find stack trace, attached logcat logs “Logcat logs”

Resolution Note:
The issue is caused by a driver bug in the Qualcomm Adreno Vulkan driver.
We sent a repro app to Qualcomm. Depending on the outcome we might implement we might implement a workaround in the engine in the future.
The customer is aware of a possible workaround for this issue from C# (clear with draw call and custom shader).
