Hi, please uninstall the Illustrator Beta from your machine and re-install it to check if it helps.
You can check the steps to uninstall the app here: https://adobe.ly/3z4sAek
Would you mind elaborating on the issue you're experiencing with Photoshop? It would be helpful if you could share your workflow in Photoshop and also share some info about the tech specs of the computer you're working on. You can also go to the Help menu in Photoshop, then System info, and copy the text. You can either paste the info in a reply here or paste it in a text file and share it as an attachment.
Thanks!
