Updated Asus AC68U with lastest firmware, now I can not access the router, user/ password not working anymore

I updated an Asus AC68U, with freshtomato-RT-AC68U-ARM-2020.2-AIO-64K.zip and now I can not access router anymore, user/ password are not working anymore.

Otherwise the router seems to be working fine. SSID, port forwarding, etc. are working fine.
