Hi,

I was trying to use Instruments on a executable Swift Package I am working on but I keep getting this error.

"Required kernel recording resources are in use by another document."

What document? I also can't profile Swift NIO's NIOHTTP1Server or a fresh iOS project using File > New > Project > Multiplatform App

I was getting this error before revoking the current certificate in keychain and setting up a new one. “Failed to gain authorization” https://developer.apple.com/forums/thread/681687

Xcode/Instruments 13.3 (13E113)

Thanks in advance for any help.

Hi there,

Do you happen to have any other windows of Instruments trying to record at the same time?
