Board
ESP-C3-32S-Kit
Device Description
Datasheet: https://docs.ai-thinker.com/_media/esp32/docs/esp-c3-32s-kit-v1.0_specification.pdf
In Arduino IDE, I have selected "LOLIN C3 Pico" with "USB CDC On Boot: Disabled".
This board works correctly in other examples under these settings.
Hardware Configuration
plain module on breadboard, nothing attached
Version
latest master (checkout manually)
revision 0ef2986
IDE Name
Arduino IDE 2.3.2
Operating System
Windows 10
Flash frequency
80MHz
PSRAM enabled
no
Upload speed
921600
Description
When LittleFS.format() is invoked, the console logs the following error:
E (618) task_wdt: delete_entry(233): task not found
[ 404][E][esp32-hal-misc.c:159] disableCore0WDT(): Failed to remove Core 0 IDLE task from WDT
Several seconds later, the board resets due to task watchdog.

Other Steps to Reproduce
I also tried on an ESP32 chip (FQBN espressif:esp32:heltec_wifi_kit_32:UploadSpeed=921600,CPUFreq=240,PartitionScheme=default,DebugLevel=debug,EraseFlash=none).
It also emits a similar error (many times), but does not cause watchdog reset later:
