This module in Drupal 10.2.x make all block titles unable to modify

I can cofirm this issue. It appears, no block settings can be changed while ajax_blocks is active.

My current workaround is:
1. Deactivate block_ajax module
2. Change the block properties
3. Reactivate block_ajax module
4. Reactivate "Load block via Ajax" checkbox for the desired blocks
