Thank you for the prompt reply!!
After downgrading to 1.0.1, I get the following error (even after starting a new unity project):
Library\PackageCache\com.htc.upm.wave.xrsdk@1.0.1\Editor\WaveXRPlayerSettingsConfigDialog.cs(95,18): error CS0117: 'PlayerSettings' does not contain a definition for 'SetVirtualRealitySDKs'
More details:
I am still using Unity 2020.3.11f1.
Just for reference (i dont know if this is relevant), I cannot find SetVirtualRealitySDKs in the Project Settings > Player menu.
For the fresh project, I just created a new project in unity and tried adding the 1.0.1 wave xr library and that error popped up.
Thanks in advance!
