dReproduction steps:
1. Open the attached user's project "ScrollRectTest.zip"
2. Build the project for Quest 1/2 and start the application
3. Point controller beam to the input field and press trigger. Observe system keyboard appearing
4. Point controller to blue "confirm" button on the keyboard. Observe system keyboard closing, and controllers are being tracked
5. Repeat step 3
6. Press Oculus Home button on the right controller

Expected result: Observe system keyboard closing. Controllers are tracked and functional
Actual result: Controllers are not tracked and the app became not functional, pressing the Home button again closes the application (See attached Issue.mp4)

Reproduces on: 2020.3.33f1, 2021.2.18f1, 2022.1.0b16, 2022.2.0a10
Could not test on 2019.4.38f1 due to downgrade errors

Notes:
-Issue reproduces with both Open XR and Oculus XR plugins
-You can refer to "test.cs" file with some status check code. After step 6 TouchScreenKeyboard.visible is still 'true', also custom plugin KeyboardChecker.java shows that keyboard status is opened (see native plugin code attached "KeyboardChecker.java")
