getAuthService authSDK returned with ZoomSDKError(rawValue: 3)

Yeeee! I resolved this problem. Like @jon.zoom mentioned, I only needed to re-sign the .app files and the command I used is codesign --force --verify --timestamp --verbose --options=runtime --sign "identity" filename.app which comes from this other post in the forum.
Thank you @jon.zoom for your help!
