Hi @laefsky,
Could you first reset Wio Terminal and then try to upload the code again?
If reset doesn’t work, enter bootloader mode, and try to upload the code again.
Note: When you enter bootloader mode, the COM port changes. So you have to go to Tools > Port and change the COM port.
The instructions can be found in the link below:
Hope it works!
Best Regards,
Lakshantha
