If your checkboxes are not grouped and have a static element name or ID, you might consider checking them through JavaScript.
In the example below, I first opened the checkbox website mentioned above, selected a few boxes, then attached it in launch browser and ran the JavaScript. It worked perfectly.
Flow Code Screenshot:

Power Automate desktop code:
WebAutomation.LaunchEdge.AttachToEdgeByTitle TabTitle: $'''Checkboxes & Radio Buttons''' AttachTimeout: 5 BrowserInstance=> Browser
WebAutomation.ExecuteJavascript BrowserInstance: Browser Javascript: $'''function ExecuteScript() {
var checkboxes = document.querySelectorAll(\'input[name=\"color\"]:checked\');
var selectedColors = [];
checkboxes.forEach(function(checkbox) {
selectedColors.push(checkbox.value);
});
alert(\"Selected colors: \" + selectedColors.join(\', \'));
}''' Result=> Result
How to copy/paste the above code into your power automate desktop?
