GitKraken does not start anymore on Ubuntu 18.04

Question

When I turned on my Ubuntu 18.04 yesterday and wanted to start GitKraken, it did not work. After I click its icon I see how the process tries to start in the upper left corner (next to "Activities") but after a few seconds the process seems to die and nothing happens. Trying to launch GitKraken from the console fails too with the following two messages:

/snap/gitkraken/58/bin/desktop-launch: line 23: $HOME/.config/user-dirs.dirs: Permission denied
ln: failed to create symbolic link '$HOME/snap/gitkraken/58/.config/gtk-2.0/gtkfilechooser.ini': File exists

Unfortunately, my Linux skills are too limited to solve this. The only thing I've tried is chmod 777 $HOME/.config/user-dirs.dirs because of the Permossion denied but that did not help.

EDIT: as terdon suggested in his comment I've made ls -ld ~/.config/user-dirs.dirs and this is its output:

-rwxrwxrwx 1 myusername myusername 633 Mai 6 10:30 /home/mayusername/.config/user-dirs.dirs

Then, I made the mv ~/snap/gitkraken/58/.config/gtk-2.0/gtkfilechooser.ini gtkfilechooser.ini.bak command and tried to start GitKraken afterwards. I did not start showing again:

/snap/gitkraken/58/bin/desktop-launch: line 23: /home/myusername/.config/user-dirs.dirs: Permission denied

The ln: failed to create symbolic link ... error from my initial post did not appear. Exe cuting ll in the directory ~/snap/gitkraken/58/.config/gtk-2.0 gives me the following output:

drwxrwxr-x 2 myusername myusername 4096 Jun  3 16:44 ./
drwxrwxr-x 8 myusername myusername 4096 Mai 21 12:28 ../
lrwxrwxrwx 1 myusername myusername   47 Jun  3 15:45 gtkfilechooser.ini -> /home/myusername/.config/gtk-2.0/gtkfilechooser.ini
-rw-r--r-- 1 myusername myusername  198 Jun  3 16:44 gtkfilechooser.ini.bak

gtkfilechooser.ini -> /home/myusername/.config/gtk-2.0/gtkfilechooser.ini is red since the file does not exist anymore. Executing the chmod command afterwards did not change anything. GitKraken does not start and outputs the same errors.

SOLVED: Had to install libgnome-keyring: sudo apt install libgnome-keyring0

The UI now comes up and works for me. Still get the following warnings, but it's working:
