After updating TiddlyRemember plugin syncing fails on Grok TiddlyWiki but works on other Tiddlywikis

See below for error info. Running win10 and Anki Version ⁨2.1.48 (fb07bad3)⁩
Python 3.8.6 Qt 5.14.2 PyQt 5.14.2

Was working fine then upgraded the plugin and boom - no work. Any ideas what I need to do?

Error message:
