RTC Watch dog Reset digital core ESP32 C3

[Basti149]

Hello,
I flashed Tasmota version 13.2.0 (tasmota32) on my ESP32 C3 on Friday. Everything went smoothly over the weekend. And as of today, the C3 can only be accessed again after a restart. Config remains.

Error message: Reason for the restart according to Tasmota Info: "RTC Watch dog Reset digital core" But what does he want to tell me?
What is the problem? After the restart everything works until it "gets out" again. It will then no longer be accessible via WiFi.

Briefly about my setup, a PZEM004t is connected to the C3 via a level shifter, DS18b20, LEDS, WS2812 and nothing more. When you restart everything is recognized and it works. Until he gets out after about 8 hours.

Unfortunately, I haven't found a solution to this error on the internet yet.

two other C3 with inputs/outputs/Leds work with Tasmota version 13.1. Could re-flashing solve the problem?
