TypeError: invalid initialization vector preventing Entra sign in on 2.18.0-insider.813

**Describe the bug**
After updating to BatchExplorer 2.21.0-insider.995, upon opening the application, I was logged out of my Entra account and asked to sign in again. However, the sign in process fails with the following error after entering my credentials and completing 2FA:

> TypeError: invalid initialization vector

Clicking 'OK' just keeps displaying the blue loading state with _'Prompting for user input'_ forever.

**To Reproduce**
Steps to reproduce the behavior:
1. Open the application on Windows
2. Complete the sign in process
4. See error

**Expected behavior**
Completing the sign in process should have signed me in and let me access the application.
