You can try getting some help on Canaans Telegram channel. If you think it is the power supply, take the Dell one, and I still have a spare one which I could give away. Other than that, if you believe you tried everything, than you may have to give up.
Give up? No. Canaan should replace the miner.
Because you've tried different PSU's my guess is that the USB-C PD connection in the miner is messed up and is not reporting the PSU capability correctly.
