Hi @belimposition Have you tried installing the operadriver separately and run it as usual.

1- Download from here https://github.com/operasoftware/operachromiumdriver/releases
2- Add the unzipped operadriver to /usr/bin or /usr/local/bin whichever is on your path (for Mac), you may need linux equivalent probably
3- Run from terminal $ operadriver --port=8899

Make sure your Gemini file has this browser configured.
I am using js format instead of yaml for config file. You can configure in yaml based on following.

opera: {
gridUrl: 'http://127.0.0.1:8899',
desiredCapabilities:{
browserName: 'opera',
ensureCleanSession: true
},
screenshotMode: 'fullpage',
},

Let me know if that helps or in case it doesnt work for you.
