moving here from TamperMonkey update crash to not duplicate the threads for this, my scripts did load, but only about half of the time - this goes for both the dashboard and the review page, hitting f5 few times worked as workaround, but it was very annoying.
i can confirm that i was getting the same error gijsc1 mentioned and linked “Uncaught pagejs missing”, nothing mentioned here nor in the github thread worked as a workaround besides exporting my scripts from tampermonkey, installing violentmonkey and importing scripts there (took like 20sec, its not as bad as it sounds! idk why i tried that one as a last resort haha). No problem with violentmonkey so far.
Thanks @Mojibaked for advice about violentmonkey and @gijsc1 for finding the error on github and linking this thread
