I get this when trying to mine Grin with RX Vega GPUs....

Bminer: When Crypto-mining Made Fast (v12.0.1-eab048c)
Watchdog has started.
Starting miner on 8 devices
Undefined but requested solver: cuckaroo29
Miner died! It will be restarted soon...

I get about 2.8-2.9 gps on GrinGoldMiner, wanted to compare it with Bminer but it isn't working.
