What are my options for extending my stay in Thailand after my education visa expires?

Hello - I’m in Chiang Mai on an education visa since almost a year (following three extensions x90 days at the Chiang Mai immigration office). My last extension expires on July 28 and as it’s been one year, I understand I cannot do another extension, but need to leave the country. As I would like to stay longer, I’m hoping that the current visa amnesty will be extended after July 31, or that borders with neighbouring countries will open up so I can do a border run. I wanted to ask if anyone would see an alternative option or possibility for me to stay in the country? Or if the only thing I can do for now is wait and see? Many thanks in advance for any advice!
