In 1964, after soloing in 3 hours on a taildragger biplane (with solo glider experience), my landings deteriorated. My instructor chopped the lesson, saying he didn't know what to do. Later that day I flew with a more experienced instructor, who'd been briefed.
Took-off, at a few hundred feet he took control, flew a low circuit, and handed me control for final. Another bad landing. Repeated 3 times. No comment from him. He now knew what I was doing wrong, and told me what to do to fix it.
A few more landings to be sure I was fixed, and I was back with my previous instructor for most of the rest of my 30 hours PPL. After allowing my PPL to lapse for 20 years, I had instruction to regain it.
What you need is a few flights with good, briefed, instructor, who can spot what YOU are doing wrong. And no long breaks. I did the PPL residential at Thruxton from 27/7 to 21/8 1964.
