Can't solo mine with Geth full node

[maxima7787]

Hi!
I donwloaded the last version Demeter (v1.12.8) to launch my local solo mining pool. I have 15 Gh/s mining power.
I launched geth with this command:
geth --classic --http --mine --miner.etherbase 0xAddress --syncmode full --miner.threads 0 -http.api "eth,net,rpc,web3,admin,personal,miner" --http.addr "0.0.0.0" --http.port 8545

After full sync and DAG file create i recieved this:
Commit new sealing work number=15,689,833 sealhash=2c1f78..b7dccc uncles=0 txs=22 gas=475,745 fees=0.00048095675 elapsed=6.215ms

Not commit new mining work.

If i try to connect mining rigs, geth give this:
Served eth_submitHashrate conn=127.0.0.1:51612 reqid=9 duration=0s err="invalid argument 0: json: cannot unmarshal hex number with leading zero digits into Go value of type hexutil.Uint64"

I tried launch geth on Windows 11, Ubuntu 22.04. Tried various miners with ETChash support like T-Rex, LolMiner, Phoenix, G-miner. But geth gave the same error.

I can't find solution, I'm searching 3 days. I can't mine solo
Please help

Hey there, I've just created a PR (see link just above) with a few commands and resources that might help. Maybe we can move the conversation there and build a useful reference together.
