Offline circulation uses a plugin, jquery.indexeddb.js, which hasn't been updated for almost ten years. There is an outstanding issue about it being incompatible with jQuery 3.6: https://github.com/axemclion/jquery-indexeddb/issues/75
Ouch, thanks for tracking that down. Does it look hard to replace?
The in-built offline circulation tool has been removed recently with bug 33961.
