Unable to upload keystore or generate a new one after SDK update

I am working on an existing app which has been redeployed under a new user, since it was previously deployed with a personal account. The first test deployment was succesful, a new set of certs and profiles was created for iOS and the existing keystore was uploaded for Android. (Almost) smooth sailing.

After updating the SDK (34 -> 37) however, I am unable to upload the keystore as before as well as generate a new keystore. I run expo build:android --clear-credentials and choose either option, in either case getting An unknow error occurred without any further information. When uploading I get the four step wizard, but immediately after that I get the message. When generating I get it right away.

Output from expo diagnostics:

Downgrading expo-cli to version 3.20.9 solved the problem :slight_smile:
