When trying to deploy a SPFx Extension tenant wide, I get an error of "Sorry, something went wrong."

The extension works locally. It also works if I install it to individual sites. We want to deploy it to a specific collection for testing and then to /sites/ after testing. I add the app to Site Contents of our App Catalog > go to deployment > specify the collection to deploy it to > hit OK > then I get this message

This method has worked well for deploying custom SharePoint apps in the past. This is the first SPFx we have tried it with.

I have also tried to role it out tenant wide by setting skipFeatureDeployment to true and checking the box for "Make this solution available to all sites in the organization". The deploy dialog box goes away but nothing installs. https://docs.microsoft.com/en-us/sharepoint/dev/spfx/tenant-scoped-deployment. I double-checked the console confirm the extension didn't get rolled out.

I have tried this with heavily modified extension and a simple HelloWorld extension. I get the same results with both.

Any help would be much appreciated!
