Hello. At some point, I had tried a migration of the 2019 Wwise project to 2021, but it seems it throws an error when once again trying to open the project with Wwise 2019.
I do have the Wwise 2019 project linked up to WAG via the Wwise Launcher, but still getting this error, in essence it can't migrate in reverse - anyone know how to solve this issue to start the project again on a clean slate with Wwise 2019?
