Latest firmware serious issue - 4.3.9_2033

I made the ultimate mistake of updating dreame x50 Ultra to the latest firmware 4.3.9_2033. The robot does not clean anymore, only cleaning few seconds, flashing purple light then blue light, then make way back to base to charge.

For vacuum only it works, but once I include mop it does not work.
Have restarted the base and restarted the robot - both does not solve it.
Please help asap.
