Open Replay Kit settings from Top menu bar Windows -> Voxel Busters -> Cross Platform Replay Kit -> Settings
Enable Android Q support under Android section
Click on Save button
Incase if your Unity doesn't have API 29 SDK, set Target API in Player Settings (under Android) to API 29
Try making a build for Android SDK update prompt from Unity
After finishing the update, you can reset it back to Automatic option for target API
