Sounds like you have two bugs.
Asking for the password twice is bug 1765261.
But it sounds like you also have a crash causing your lost session so...
-----
Thank you for taking the time to report this bug and helping to make
Ubuntu better. However, your bug report is missing crash details. In
order to debug a crash we will need a crash report. To create one,
please follow these steps:
1. If you are not running a future development release of Ubuntu then apply the
workaround from bug 994921.
2. If you are running the Ubuntu Stable Release you might need to enable apport
in /etc/default/apport.
3. If the crash is in Xorg then uncomment this option from
/etc/gdm3/custom.conf:
# Additionally lets the X server dump core if it crashes
#Enable=true
4. Reboot.
5. Reproduce the crash.
6. Look in /var/crash for crash files and when found, run:
ubuntu-bug /var/crash/YOURFILE.crash
7. Add a comment here telling us the ID of the new bug that was created in step
6.
Please take care to avoid attaching .crash files to bugs as we are
unable to process them as file attachments, and doing so is also a
security risk for yourself.

Title:
Resuming resets my session
Status in xorg-server package in Ubuntu:
Incomplete
Bug description:
I installed 18.04 from scratch a day after it got released.
Twice per day I close the lid of my laptop and open it again after.
Usually it immediately asks me for the password and brings me back to
what I was doing.
But 3 times so far, it took a minute before showing me a login screen
(like if I had not yet a session) asking me to choose my user (there
is only one user), then enter my password. It then starts to load...
and asks me for my password AGAIN. Then it shows my desktop, but
everything I was doing before is gone, no more open windows. When I
start Firefox it asks me whether I want to restore my tabs. When I
open Byobu it shows my tabs as I left them.
