Thanks for the detective work! I was running into the same issue. Interestingly, on the RX pin I was reading back whatever I wrote on the TX pin. It worked in v5.2.1, and then broke on some of our boards with this specific pin out with v5.5.1.
Thanks to you, ended up fixing it like this:

Wireless Coex Panic in 5.1.2
Hey everyone,
we've been using WifiMesh and BLE side-by-side for a while now on 5.0.x. It's been working fine and without any major issues (just the to-expected performance degradations).
We've recently switched to 5.1, and we're now seeing kernel panics if bluetooth is advertising and wifi mesh ...

ADC Timeouts on ESP32-S3
Hi,
We're using the ESP32-S3-WROOM-1-N16R2 for our boards. It is connected to two PT103J2 Thermistors on GPIO4 and GPIO5. We're using ADC continuous mode to sample them.
We're using the official release branch of ESP-IDF 5.1.2 commit 482a8fb2d78e3b58eb21b26da8a5bedf90623213 (https://github.com ...
