我测试了下最新的mysql 8.0.22在mg环境下的binlog
my2sql -user admin -password xxxxxxx-host 127.0.0.1 -port 3306 -work-type rollback -start-file mysql-bin.000118 -start-datetime "2021-01-06 18:50:00" -stop-datetime "2021-01-06 18:55:00" -output-dir .

我这边不行，mysql 8.0.22 mgr环境下exit thread to write redo/rollback sql into file
exit thread to write redo/rollback sql into file 是正常的日志哦，如果没有sql解析出来，就确认下这段区间是否有binlog event，也可以调整下区间，多测试几次吧。
以下是用mysqlbinlog解析的和您工具的截图，请参考
