Problem editing user quota – "User with this email already exists" error

[archos]

Hi,
I’m not sure if this is related to the Cloudron update to version 8.3.1, but I’ve encountered an issue in the PeerTube app.

When I try to edit an existing user to increase their video quota (e.g. max upload size), after clicking Save, I get the following error:

User with this email already exists

However, I’m not changing the email address – only the quota field.
I’ve tested this in different browsers (Firefox, Vivaldi, incognito mode), but the result is always the same.

Backend returned code 409, errorMessage is: User with this email already exists.

This is not a Cloudron issue — it appears to be a bug in PeerTube itself.
The issue has already been reported and confirmed by the developer:

Same problem in my peertube instance.
