Ubuntu 20.4 login

Hi,

I use VMware Workstation 15 Player to run Ubuntu in Windows. Since 2-3 weeks, I am no longer able to login. Once I enter the password, it returns me to the main login page. I searched for a solution but unfortunately I can not log into the Shell to check the .Xauthority file as suggested by some people. I have Lenovo laptop and used Ctrl Alt F3 key combination with no luck. Any hints please?

Thanks in advance
