Death Adder v2 Pro Not Detecting

I bought a Death Adder v2 Pro in late 2020 but now have several issues rendering it unusable:
1. Connecting via wireless dongle: Mouse turns on and RGB light pattern initially lights as normal, but:
a. Mouse movements and button clicks do nothing
b. Razer Synapse does not detect mouse
c. Windows settings does detect mouse
d. Mac settings does detect mouse
e. Mouse does not go to sleep even while not moving until it runs out of battery
2. Connecting via Razer USB power cable: Mouse turns on and RGB light pattern lights as normal, but:
a. Mouse movements and button clicks do nothing
b. Razer Synapse does not detect mouse
c. Windows settings does not detect mouse
d. Mac settings does not detect mouse
3. Attempting to connect via Blue Tooth: Mouse turns on but shows normal RGB light pattern instead of the Blue Tooth light pattern, also cannot detect device on computer

I have tried the above methods on multiple computers and on Windows 10, 11, and MacOS. When I tried updating the mouse firmware, I could complete the steps up to updating the wireless mouse dongle, but the update wizard could not detect the mouse over the provided charging cable for the steps to update the mouse itself.

Any suggestions on how to fix the mouse, or should I just get a new one? Also, any thoughts on what may have caused this issue?
