GDM3 stuck in a login loop

HI everyone .

So I've been using GNOME desktop environment since several months and everything was working fine and I installed PyCharm and added included it under $PATH and 20 minutes after that , my terminal asked me to chose between "lightdm" and "sddm" and there was no option to select my current display manager, so i selected "lightdm" and everything worked fine , however when i tried to login using sddm or gdm3 i was stuck in a "login loop" even after entering the correct password i was shown a black screen for few seconds and after that i was re-directed back to the login screen . So , this is my current issue :

Things that I have tried but which didn't ended up fixing the issue .

• Purge removed gdm3 several times and re-installed it .
  • • Rebooted several times
    • I had edited my .bashrc file to include /snap/bin under echo $PATH , removed it from .bashrc but /snap/bin/ was still present after reboots , so searched it and it was dynamically added to a file under profile.d , removed it from their and /snap/bin was removed from echo $PATH (I thought about this since /snap/bin directory was not present in $PATH of lightdm but it was present in gdm3 and sddm but it didn't ended up fixing the issue)
    • Gave all the permssions to .Xauthority file under /home/username directory and saw that .Xauthority was present under /var/lib directory of lightdm but was not present under /var/lib directory of gdm3 so included it there , still didn't work .
    • Made sure that /tmp had all the permissions "drwxrwxrwt" 6)Removed .Xauthority from home directory of gdm3 but placed it under /var/lib , didn't work . (Since i didn't wanted to completely remove it)
    I've attached the screenshots of .xsession-errors and the issue that i'm getting under below link :

    I did "sudo apt-get remove qemu-system-data" and removed it and rebooted as well but it didn't seem to work however I got new xsession-error logs

    I'm not able to comprehend the required next steps to take , i tried referring the x-sessionerror.old log it does show something related to qemu.desktop but i wanted to check with you people before making any further changes .
    
    Edit: Currently everything is working fine in lightdm environment however gdm3 and sddm are not working which is the issue and i tried again to give full permissions to .Xauthority under /home/username and rename it as well but it didn't worked .
    
    If there are some additional logs i need to look into , please educate me on those i'd love to go through those logs and figure out the cause of this issue .
    
    Thank you so much for looking into this .
