No admin portal after update to 2026.2.0-azure

We've updated our container from 2026.1.7-azure to 2026.2.0-azure

The webapp restarted successfully, but we are not able to open de /admin pages. The page shows an empty page, no errors are shown.
Direct links to pages in the admin portal, e.g. /admin/platform/logging, will also show no information and the page stays empty.

We reverted the image back to 2026.1.7-azure, then the admin portal works again.

The dashboard (apps) are working properly.
