I went to my local immigration few days ago, my friend who does not speak very much english was in the same boat it sounds, was on non b for a year then covid came, when it came time to renew they wanted 4 thai staff and social etc to be paid so he did not have tihis and went to covid extension when the full covid thing happend, that was march last year, now they say unless he goes back and does his full non b and workpermit etc, which he cant his business is gone he needs to leave before 25th, they will only give him a 7 day extension, they also noted that if he for say went to cambodia and tried to come back on visa exempt or on arrival they would see the covid extensions and his last non b and would not grant him entry , my experience a few days ago
