Start by reproducing startup with BotSentry 9.8-THANATOS on Folia 1.21.11 and follow the stack trace from CraftScheduler into the BotSentry entry points. Determine whether the plugin supports Folia and verify that the server starts without this exception; if support is not intended, document that limitation.
