Sense stopped taking code after attaching battery

Hi,
Was playing around with the ESP32S Sense yesterday and it was working just fine. Today I soldered on a battery and I can’t seem to be able to upload code to it anymore. I get one out of two errors:

A fatal error occurred: No serial data received.
A fatal error occurred: Could not open COM7, the port doesn’t exist

I’ve tried restarting and rebooting. Nothings works. Any idea what might be wrong?

Hi there,
Remove it , is it backwards? , any solder bridges? Those ESP’s are not real tough on handling too. If it was soldered on in reverse and a USB was plugged in , it’s Toast maybe?
break out the magnifier and give it a visual inspection. Did it get warm, too warm to the touch?
HTH

Please use this way to solve the problem of not being able to upload the program or no port
