I cannot upload to board. It was fine yesterday. How can I fix this? Error message:

avrdude done.  Thank you.



Problem uploading to board.  See https://support.arduino.cc/hc/en-us/sections/360003198300 for suggestions.

loopback test does not work. when I click on send, tx and rx lights blink but message does not appear below. these lights blink so quick and not as bright as other lights on the board (it's like 10% bright blink). They blink as many as I click on send from my computer.

OP states they are using an UNO!

Uninstall the windows store version of the software, and install a fresh version from the website, Also, restart your computer.

Make sure that there is NOTHING connected to pins 0 or 1 on your UNO.

I already did that. unfortunately did not fix the issue. I also connected the board with different usb cables and tried on another computer as well. my other arduino uno works just fine though.

Use your other arduino to reburn the bootloader.

Unfortunately, you can get this result even with a perfectly working board when using the cheap derivative boards with the CH340 USB to serial adapter chip like the one you have. So you should not pay any attention to a failed loopback test on this board.

would that fix my upload issue? I'm not familiar with it. Like this video? Burn Bootloader using 2 Arduino uno very Simple way arduino as ISP - YouTube

Is there a chance to damage my working arduino uno with this process?

still need help

It might.

Well, if you wire it wrong and create a short circuit then you could damage it. But that is always the risk we face while working with electronics. There is no special danger of damage from this procedure though.
