How to reproduce:
1. Create and open a new project
2. Install the Input System package
3. Open the Project Settings > Input System Package and click on the “Create and assign a default project-wide Action Asset” button (this will create an “InputSystem_Actions“ Asset)
4. Create and open a new Input Actions Asset in the Project tab
5. Create a new Action Map in the Project Settings Window by clicking the “+“ icon
6. Immediately copy and paste the newly created Action Map into the new Input Actions Asset
7. Observe the Console
Expected result: Nothing is logged
Actual result: Three errors are logged
Reproducible in: 1.8.0, 1.11.2 (6000.0.27f1, 6000.1.0a4)
Could not test in: 1.11.2 (2021.3.46f1) (Unable to paste the newly created Action Map), 1.11.2 (2022.3.52f1) (Unable to right-click on an Action Map)
Reproduced on: Windows 11 Pro (23H2)
Not reproduced on: No other environment tested
Notes:
- If the reproduction is not successful on the first try, close and open both the Project Settings and the created Input Actions Asset and repeat steps 5-7
- Logged errors are of types “NullReferenceException“ and “Retrieving array element that was out of bounds“ (twice)
- In versions 1.8.0-pre.2 and below, the testing became unreliable, as the Copy and Paste functionality did not exist, and project-wide actions were not available
