there have been many reports over the last few months, but most of them are from people who left and came back immediately. There was half a plane of people from Vietnam who were refused entry and sent back to Vietnam that had Covid extensions in their passports.
Just be prepared to be pulled aside and asked a lot of questions and answer why you were in Thailand for so long and why you're back already. If they can't find an easy reason to deny you entry, they will probably let you in.
I had one Covid extension in my passport when I entered last November with a tourist visa after being gone for 6 months and they still pulled my side and asked me questions for 30 minutes.
