Time Profiler "Required Kernel Recording Resources Are in Use" Error Hi, I'm using XCode 12.5 on Big Sur. When running the Time Profiler, I'm getting an error "required kernel recording resources are in use by another document". I tried restarting XCode and my computer but it still didn't work. Any idea why? Developer Tools & Services Xcode Instruments Xcode 11 0 7.2k Jun ’21
