Make sure you have "com.apple.private.allow-explicit-graphics-priority" entitlement and IOKit headers imported.
Patch for this bug was released with iOS 14.7.1 less than 2 hours ago. Might be useful for a jailbreak but not sure due to the entitlement check.

When will the jailbreak be downloaded without a computer? I hope it will be soon, God willing. Good luck and thank you
