• Set weblog to 4 and then, when you experience your issue, provide the output of the Console log:

  Console output here:
No output - immediate freezing of Tasmota

TO REPRODUCE

Steps to reproduce the behavior:
Console command:

displaytext [f1l2c1Ci11Bi14p34]1...5...10...15...20...25...30...35...40...45...50...55...60...65...70...75...80...85...90...95..100..105..110..115..120..125..130

EXPECTED BEHAVIOUR

A clear and concise description of what you expected to happen.
The character string should be truncated to prevent freezing.

As we enabled the watchdog timer for ESP32 in v14.0.0.1 the freeze should now result in a watchdog restart. The same command does indeed start the watchdog on an ESP8266.

I'll fix the watchdog by fixing the command displaytext now.
