Sorry to hear about this experience. Would you mind trying a clean reinstall of the RX580 drivers, rebooting your computer, and relaunching Illustrator to check if it helps?
Also, try resetting Illustrator's preferences by following the steps shared in this article (https://helpx.adobe.com/illustrator/kb/troubleshoot-preference-issues.html) and sharing your observations. Disclaimer: Please note that resetting preferences will remove all custom settings, and Illustrator will launch with the defaults. You may take a backup of these settings from the location mentioned in the article.
