Material that has properties with same name as builtins will break lots of things
To reproduce:
1. Open "uvbug2" project attached in comment
2. open repro scene and hit play
-> The uv scroll from right to left + speed is constant (CORRECT)
3. Exit play mode, build a standalone player, run the player
-> The uv scroll from top-right to bottom-left + speed is accelerating (WRONG)
4. Go back to the editor, select material "mat1" in Project view
5. On the Inspector, click on the gear icon and click "Reset"
6. The material will be reset. Type 1 for U Speed, 0 for V Speed, use "Default-Particle" as the noise texture on the material
7. hit play
-> The uv scroll from right to left + speed is constant (same as step 2) (CORRECT)
8. Exit play mode, save scene, build a standalone player, run the player
-> The uv scroll from right to left + speed is constant (same as step 2) (CORRECT)

- [Android] Stage information is not logged when Log Shader Compilation is enabled
- [Vulkan] The memory allocation increases rapidly when there are multiple (three or more) Real-Time Reflection Probes in the Scene
- [macOS] Library folder of the opened project can be deleted which leads to the crash

Resolution Note:
This issue is actually caused by saved Material properties names conflicted with builtin shader variable names.
Easy workaround would be resetting the Material:
1. Select the material
2. On Inspector, click on the gear icon on top left > Reset
OR
1. Select the material
2. On Inspector tab > right click > Debug
3. Saved Properties > Floats, remove the items that has conflict, i.e. _Time
