Can't sync with programmer Arduino Uno
Sometimes boards can glitch depending on wear and tear or on how well they have been manufactured. Personally I always buy boards direct from the Arduino store and  I have never had this issue. One thing that could help is placing a 0.1 uF capacitor between the +5V pin and ground and another between AVcc and ground. There will be some on the PCB already but this can help in some cases. Another thing that can help is pressing the reset buttom just after pressing upload on your PC.
Unfortunately, when out of sync errors occur it can be heavily luck based as to what works and how long it takes. Hopefully one of these tricks will work! But like you say, if other boards are working fine then it could just be bricked
