ESP32 C3 unable to upload from web

Hi,

I successfully flashed various ESP32 from web, but this time I am unable to upload firmware for a Seedstudio ESP32 C3:

Failed to initialize. Try resetting your device or holding the BOOT button while selecting your serial port.

Is there a trick to make it work?

I tried to upload with esptool, but after flashing:

Disconnected.

I used

esptool.py --port /dev/tty.usbmodem14101 --chip esp32c3 --baud 921600 --before default_reset --after hard_reset write_flash -z --flash_mode dout --flash_size detect 0xe000 /Users/Downloads/boot_app0.bin 0x1000 /Users/Downloads/bootloader.bin 0x8000 /Users/Downloads/partitions.bin 0x10000 /Users/Downloads/firmware.bin

All files were from esp32c3-dev-m1-ble build, except boot_app0.bin which I downloaded from here (linked in the wiki).

I am having the same issue, did you come across a solution? I have been trying to build from the web and then upload the binaries but have not had any sort of success at all either.
