### What Happened?

When typing "cmd-enter" on a exisiting block, nothing happens.

### Reproduce the Bug

1. Create a new block.
2. Hit "control-enter".

Then nothing happens.

Error console does provide some clues, I guess.

### Expected Behavior

Creation of task.

### Screenshots

### Desktop or Mobile Platform Information

- MacOS 26.2
- Logseq app 2.0.1-alpha+nightly.20260416 (9804728-dirty)

### Additional Context

I am long time user of logseq. Years. This issue may be related to the fact that this database was imported from Markdown to SQLite about 4 or 5 months ago.

### Are you willing to submit a PR? If you know how to fix the bug.

Start with the db-worker.js stack trace, especially set_block_property_BANG_ and batch_transact_with_temp_conn_BANG_, and trace the task-creation shortcut from there. Reproduce the failure using the reported control-enter or cmd-enter steps and inspect the error console. Done means creating a task from an existing block succeeds without the reported property error.
