with the border now open, there are no restrictions to go home easily. 20k infections a day is actually a very low number. Infections in Thailand are slightly higher than that, so why do you want to stay in Thailand? It is not any safer. Most likely the next stamp you will get from immigration is a 7 days to leave Thailand stamp, as there are no restrictions, or difficulty, in returning to Malaysia. Cross the border, get your ThaiPass, and covid insurance, and return on a tourist visa. Remember, if you get mad at immigration they will refuse you everytime. A covid extension is up to immigration in every case. It is not automatic. Also remember that all immigration computers are on the same network, so every immigration has your records if they flagged you to leave.
