Reproduction steps:
1. Open the “ReproProject“ project
2. Select the “Player“ GameObject in the Hierarchy window
3. Change the “Actions“ property under the “PlayerInput“ Script to “Actions Asset“, and then back to “Project-Wide Actions“ in the Inspector window
4. Open the Project Settings window (Edit > Project Settings)
5. Reset the Input Actions in the Input System Package category by pressing the three dots on the top right and selecting the “Reset“ button
6. Delete the “WASD” Binding from the “Move“ Action in the “Player“ Action Map
7. Repeat step 5
8. Enter Play Mode
9. Press the “W” or “S“ keys to move the “Player“ GameObject
10. Observe the Game view

Expected result: The “Player“ GameObject moves according to the key presses
Actual result: The “Player“ GameObject doesn’t move

Reproducible with: 1.8.0-pre.2 (2022.3.19f1, 2023.2.8f1, 2023.3.0b5)
Couldn’t test with: 1.6.3, 1.7.0 (2021.3.34f1, 2022.3.19f1, 2023.2.8f1, 2023.3.0b5), 1.8.0-pre.2 (2021.3.34f1) (due to Input Actions not existing under Input System Package category in Project Settings)

Reproducible on: Windows 11 Pro (22H2)
Not reproducible on: No other environment tested

Note:
Changing the “Actions“ property under the “PlayerInput“ Script component on the “Player“ GameObject to “Actions Asset“ and then back to “Project-Wide Actions“ after step 10 fixes the issue, and the player moves according to the “W” and “S” key presses again
