Hi @sleemand, @ChanduMohammad, @Santan.B, @kwertie, @miguelroman, @Joseph Raja, @andrew123 

You can try following method till there is a permanent fix to this.

To regain access to the Control Room UI, refresh your browser. Navigate to the desired dropdown using keystrokes (TAB, SHIFT-TAB) without clicking on the problematic dropdown. Then, utilize the UP-DOWN arrows to make your selection.

or if policy allows 
 

Run below script in your browser console after you login to your automation anywhere instance. This will remove error for this session  
=================================================================
function removeAriaOwnsAttribute(element) {if (element.hasAttribute('aria-owns')) {         element.removeAttribute('aria-owns');     } } function mutationCallback(mutationsList, observer) {    mutationsList.forEach(mutation => {             removeAriaOwnsAttribute(mutation.target);     }); } const observer = new MutationObserver(mutationCallback); observer.observe(document.documentElement, {     attributes: true,     childList: true,     subtree: true,     attributeFilter: ['aria-owns'] });             ================================================================
