2. Go to Edit > Project Settings... > Player > Publishing Settings and enable Split Application Binary
3. Go to Build Settings and enable Build App Bundle (Google Play)
4. Build the project
5. Convert the .AAB file to a .APKS file using the command 'bundletool build-apks --bundle=/PathTo/project.aab --output=/PathTo/project.apks'
6. Connect an Android device to your system
7. Install the project using the command 'bundletool install-apks --apks=/PathTo/project.apks'
8. Launch the installed application

Expected result: The application launches without any issue
Actual results:

- The above Unity versions and Android devices reproduce the issue according to the user
- The reproduction steps are written here in case a reproduction project appears down the line or is located somewhere unreachable to CQA
- Following these reproduction steps while using an empty Unity project does not result in any of the errors or freezing
- The problem is inconsistent and reproduces easier on certain devices rather than on others
- Inae Kim mentioned that they were able to reproduce Case_2 result of the issue
- The Case_1 and Case_3 results occur once in 10-50 times
- If the '--mode=universal' flag is used in step 5, the issue disappears, however, the user cannot use the flag due to application upload restrictions
