You have a good reply from

. Get a tourist visa. And be prepared to be questioned upon your return to Thailand by Thai immigration.
As you have stayed in Thailand a long time using the STV and COVID extensions.
Be prepared with a Plan B if you are denied entry...as others who have similar Thai immigration history as yours have been denied entry recently.
Suggest you read the

that I placed on your post. CLICK on it and you can read other posts from those attempting to do as you are wanting to do. Good Luck.
