Pages go empty after update, force reload solves it temporarily

Hi , I am having this issue since the update a few days ago. Pages go empty after a short while (and the theme goes back to standard eventhough it is set to the "minimal" community theme). Force reload brings the pages (and the chosen theme) back but only for a few minutes. I only have this problem on my macbook, on my iMac this doesn't happen. Both are synced through iCloud where the Obsidian vault resides. Any ideas or suggestions would be very welcome, thank you!
