Regression
Yes
Editor with two locked Project tabs opened throws NullReferenceException in the Console when selecting an error in the Console window
Reproduction steps:
# Open the user attached project
# Open the “SampleScene” scene
# Enter the Play mode
# Select the error in the Console window
Expected result: NullReferenceException is not thrown in the Console
Actual result: NullReferenceException is thrown in the Console
Reproducible with: 2022.1.0b1, 2022.1.20f1, 2022.2.0b11, 2023.1.0a14
Not reproducible with: 2020.3.40f1, 2021.3.12f1, 2022.1.0a16
Reproduced on: Windows 10
Note: in 2022.2 and 2023.1 sometimes, the Console window will bug out and won’t show anything unless opened again, behavior is intermittent, no clear workaround for this
First few lines of error:
NullReferenceException: Object reference not set to an instance of an object

Thank you for reporting this, I too have found this issue. It would seem that I needed to enter playmode atleast once before the error showed up on a fresh boot

Thanks for posting this! I was having the same error: 4 project views, 2 were locked, and unlocking one fixed it. My issue started happening when I called EditorGUIUtility.PingObject. Then it would throw a similar error whenever I clicked on something and changed my selection. Here is the callstack of that initial PingObject call (wish I could pastebin this):

After unlocking one of the Project tabs, the error seems to persist, and I still cannot correctly ping the asset I clicked on.
