Ansel wont work if the same project is still open while running the packaged version.
Found in 4.20 CL# 4369336, 4.21 CL# 4753647, 4.22 CL# 6574378, 4.23 CL# 6599617
An error message will pop up saying "a supported game is required to use this feature"
Ansel would work
Close the project in the editor before opening the packaged version
