Terminal Gibberish?

I'm getting a bunch of gibberish when connecting that seems to be blocking any actual usage. Wondering where I went wrong.

I'm using a HiLetgo ESP8266 ESP-12E with my Macbook Pro M1. I am able to successfully run example sketches via Arduino IDE so I don't think it's a hardware issue.

Here's the flash command and output:

[~/Projects/rr-buttons/esp8266-firmware]­ $ esptool.py \
>   --port /dev/tty.usbserial-0001            \
>   write_flash                               \
>   --erase-all                               \
>   --flash_freq 80m                          \
>   --flash_size 4MB-c1                       \
>   --flash_mode qio                          \

But when I go to connect via screen I get gibberish before the Espruino prompt and the terminal becomes unresponsive to any keyboard input.

The gibberish varies but I haven't figured out any way to decode it other than thinking "that looks a lot like control characters...":

Any ideas what I screwed up?
