I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

For information I get the crash only on the simulator and not from a device. On the simulator I tested on a: iPhone 12 mini / iOS 14.5

Hi @bluelagon, I've tried to enable the Address Sanitizer via Edit Schemes and run my sample app to iPhone 12 mini simulator, but I wasn't able to get the same crash. Have you tried to update your SDK using the pod update command and see if the issue persists? Also, you may share the full error logs you've encountered. Thanks.

Thank you @rizafran. I did a pod update and updated the Performance SDK to 8.6.1 and it fixed the problem. Thank you for your help.
