Problem in Uploading Sketch in Arduino Uno - arduino-uno

Question

I'm using arduino for around 3-4months. Now I'm facing issue in uploading sketch in arduino Uno.
This happened after using atmel-ice for debugging. I was trying to debug the code using atmel-ice for the first time in atmel studio. I followed tutorial video on YouTube for connecting and debugging arduino uno using atmel-ice debugger. It never started debugging it turned off with an error. After that I tried to upload sketch in board using arduino ide as well as atmel studio and using ice also but it cannot upload the sketch and in atmel studio I could read the device signature previously after trying debugging, I cannot read the device signature. I never touched the fuse settings in the atmel studio for arduino. It was default.

avrdude done. Thank you.
Getting above errors. in arduino ide.
I read similar issues with others some of them were saying it is in debugging mode. But after restarting it should go out of that as uno resets. I've also checked loopback it's working. This happend with my 3 of uno boards I've only 1 left now. How can I solve the issue. I tried burning boot loader also but that also got error. I think may be fuses are the issue. How can I Solve this issue.
if I'm using FTDI232 programmer it showing
avrdude: ser_open(): can't open device "\\.\COM13": Access is denied.
avrdude done. Thank you.
This Error.
After Trying using ftdi232 got

Answer 1

Make sure that there is no input on the Tx/Rx pins then it works. I've tried this and board started working.
