Emulator stuck at "waiting for app to load"

[tjvanderende]

Description
The radon ui panel boots up the device, but gets stuck on the message "waiting for app to load"
Environment

• v0.0.20
• Expo: 51.0.3 & 0.74.5

Please let me know what other data you need. I couldn't find any error message (when you press the "wating for app to load" it doesn't show any issues).

Thanks for reporting. Would you mind trying this again with 0.21?

If the problem persist please take a look at our troubleshooting guide. Specifically section about accessing extension logs here https://ide.swmansion.com/docs/troubleshooting#6-accessing-extension-logs – would be helpful to us if you could share these logs for us to investigate.

Hi, I am getting this same error. I have multiple schemes for my iOS project. The project builds up and gets stuck on the screen which shows a message "Waiting for app to load". In the extension log, I am seeing the error.

Anyone here can reproduce this on version 0.22 ? We found out that in many cases this issue would occur due to metro cache conflicts. In 0.22 we fixed this issue by making IDE use a separate metro cache store.

@santimone – I see you're experiencing this on Windows, and the root cause can be likely the same. Apparently we haven't yet published 0.22 for Windows so until it is out, there's no way for you to try it
