So is there a question or something we can help you with? We are not Adobe employees here, but just a forum of people trying to help. There is the https://illustrator.uservoice.com that you can address this issue to however.
Sorry to hear about your experience. Would you mind sharing the version of the OS? Do you see this behavior while working on a specific file? Do you have Smart Guides turned on(as asked by @Ton Frederiks)?
I'd request you to share a small video of your workflow or screenshots so that we can understand the issue better & work on it.
