Mailspring encountered errors syncing this account - Suspect Keyring issue

Today after launch mailspring all accounts (gmail, yandex, others) appear marked “red” in manage screen due to sync/auth fail.
Mailstpring worked properly until yesterday, I haven’t changed anything in its config, nor on my system.

  • mailspring version: 1.15.1-cb02bf10
  • system: Slackware64 GNU/Linux 15.0
  • graphic environment: X11 + dwm
  • launch command by bash script:

mailspring --password-store="gnome-libsecret"

On the red warning “Several of your accounts are having issues” I chose I “manage”. All accounts are marked red. Tried to re-connect but after a gmail account re-login to trust mailspring, an error pops up:

Mailspring could not store your password securely. For more information, visit https://communityt.getmailspring.com/t/password-managment-error/199

Here I read:

Other Desktop Environments

When using a desktop enviroment that is not Gnome or KDE based such as LXDE, ensure that you followed the steps for the Gnome Desktop Environment. Then, try running Mailspring from the terminal while forcing Mailspring to encrypt your passwords using the gnome-libsecret backend:

mailspring --password-store="gnome-libsecret"

I encountered this issues times ago, and I solved as explained, by adding --password-store="gnome-libsecret".
But now I’m using gnome-libsecret for keyring yet… I just tried to reboot my system, but with no luck…

Any suggest?
Thanks in advance

An update:
today after system boot, Mailspring works properly.

I don’t know why the hell it failed to sync yesterday… Any ideas would be appreciated.
