State token does not match when using OpenID to login

## Steps to reproduce

Open App
Try to login using the OIDC provider configured using the OpenID Connect User Backend app

## Expected behaviour

I expected to be logged in

## Actual behaviour

I got an error saying "State token does not match"

### Device information

Device: iPhone 1
iOS version: 18
Talk version: 20.0.2
NextCloud version: Nextcloud Hub 8 (29.0.5)
OpenID Connect user backend version: 6.1.1

### Observations

We can long just fine using the app password or the QR code or even for those users not configured via OpenID Connect.

Unfortunately I don't have access to logs as I'm using the hosted Storage Share from Hetzner, but I can ask if needed.

I've been through https://github.com/nextcloud/talk-ios/issues/1017 and this is why we used the QR code.

Thank you for any help!
