Yes, you should bump the version to get the fix.
Assuming you’re getting the same deserialization error from anvil_extras.storage
Anvil-extras was using a type check rather than an isinstance check when deserializing objects from indexed-db.
The return type from javascript changed and this led to the errors
Edit:
We’ve pushed the fix to 2.4.1 as a patch on 2.4.x
This way you don’t need to bump the minor version
