Laos is probably the “safest bet” to do a border bounce with Covid extensions. No reports of issues re-entering there.
Many reports of trying to re-enter via other borders or airports.
Why would they give you hassle? Well because the covid extensions were just basically “tourist visa extensions” open to everyone. Some people have lived here for 2 years plus on them. They’re not tourists. Immigration will likely see them as trying to stay long term on the wrong visa type and almost certainly working illegally.
