Fails to load block - block/collapsed should be marked as db/index true

Nobody has claimed this yet.

### What happened?

Certain pages fail to be loaded, I only see a blank page and have to restart Logseq after (no UI visible). Even after a restart the page cannot be loaded. I created the page a while ago and only when accessing it it fails.

Unfortunately, I cannot share the contents of the page but will see if I can work on a minified example.

The error message is:

Start from frontend.db.model/get-limited-blocks in the stack trace and trace how :block/collapsed? is accessed, then inspect the database schema/index definition for that attribute. Reproduce by opening the affected page if a usable example becomes available; done means the page loads without the reported index-access error.
