"There was a problem loading the requested app."

Was getting the error "There was a problem loading the requested app." when trying to load my expo project. After trying many things, what finally worked for me was deleting the .expo folder in my project. Just a heads up to others!

In case any expo devs want to look into this more:

From my old .expo:

.packager-info.json:

{
  "expoServerPort": null,
  "packagerPort": null,
  "packagerPid": null,
  "expoServerNgrokUrl": null,
  "packagerNgrokUrl": null,
  "ngrokPid": null,
  "devToolsPort": 19003,
  "webpackServerPort": null
}

settings.json

{
  "hostType": "lan",
  "lanType": "ip",
  "dev": true,
  "minify": false,
  "urlRandomness": "wt-tcb",
  "https": true
}

several packager-info.json.XXXXXXXX files:

{
  "expoServerPort": null,
  "packagerPort": null,
  "packagerPid": null,
  "expoServerNgrokUrl": null,
  "packagerNgrokUrl": null,
  "ngrokPid": null,
  "devToolsPort": 19002
}

In my new .expo:
packager-info.json

{
  "devToolsPort": 19002,
  "expoServerPort": 19000,
  "packagerPort": 19001,
  "packagerPid": 4075,
  "expoServerNgrokUrl": "https://sh-n79.raphaelrk.hangline.exp.direct",
  "packagerNgrokUrl": "https://packager.sh-n79.raphaelrk.hangline.exp.direct",
  "ngrokPid": 4090
}

settings.json

{
  "hostType": "lan",
  "lanType": "ip",
  "dev": true,
  "minify": false,
  "urlRandomness": "sh-n79"
}

Edit: just ran into this again. I suspect it may be because Iā€™m running expo start --https. I deleted my .expo folder and was still having the issue. Deleted the .expo folder and ran expo start instead and it worked.
