The reason for it taking so long is in the logs

2023-09-26T14:03:12.702-07:00 WARN 90903 --- [onPool-worker-2] c.v.f.s.frontend.TaskUpdatePackages : package-lock.json is missing from this project. This may cause the npm package installation to take several minutes. It is recommended to keep the package-lock.json file persistently in your project. Please stand by...

These errors seem to be something completely different and are probably resolved after a restart

[marcushellberg]

I only ever got a blank page. I didn't get the page telling me that I should run a gradle command to init the app.

Was this resolved in 2.3 alpha 6?

Cannot reproduce it with Hilla 2.5.5. Application takes some time, but runs. I used the exact configuration provided above.
