I am using ESP32 WROOM 32U(4MB)
Following are the errors shown on Serial Logs

Not sure what your question is, exactly, but I am guessing you aren't happy about your ESP32 rebooting.

Looking at your logs:

rst:0x7 (TG0WDT_SYS_RESET)
This shows you that your first reset was because of the TG0 Timer Watchdog reset.

Google that - maybe check https://esp32.com/viewtopic.php?t=7980

Next one was a reset (rst:0xc (SW_CPU_RESET))

Then a rst:0x10 (RTCWDT_RTC_RESET)
Maybe here: https://esp32.com/viewtopic.php?t=25729

The RST value is a register which stores the reason an ESP32 reboots, and it's shown as above. You can find all the values in the API documentation fpr esp_reset_reason here : https://docs.espressif.com/projects/esp-idf/en/v5.3.1/esp32/api-reference/system/misc_system_api.html?highlight=esp_reset_reason#_CPPv416esp_reset_reasonv

Hope this helps.
