Cannot add new tasks after update to 5.10.4

I don’t know if this should be added here or a new topic should be created. Also let me know if I should report a bug on GitHub.

Since upgrading to v5.10.6 the Tasks page is now blank - nothing is visible and you cannot create new tasks. Going back one page, you must do a browser reload for other pages to be visible again.

Edit: I should note that this also relates to the topic that I linked below.

Edit 2: Also of note, only the React web app seems to be affected by this problem - which is what I prefer to use. The IN Flatpak, flutter app displays the Tasks page correctly.
