Linux Desktop AppImage 3.14.0 amd64 can't remember authentication

[tassoman]

After updating from 3.13.x to 3.14.0, my profile's token can't be remembered. Always opening web browser authentication process.
I read sdout logs and seen configuration can't be moved from .local/share/Nextcloud to .config/Nextcloud so moved by my self.

Since then, app is crashing:

Failed to initialize instances shared memory:  "QSharedMemory::handle: doesn't exist"
Path override failed for key base::DIR_APP_DICTIONARIES and path '/tmp/.mount_NextclMfmKFP/usr/libexec/qtwebengine_dictionaries'

[0925/095730.164100:FATAL:v8_initializer.cc(516)] Error loading V8 startup snapshot file
Rilevato trace/breakpoint

So I tried to delete both directories, plus .cache/Nextcloud but, no results.

Environment is Debian Testing amd64 XFCE desktop

What's happening? Is 3.14.0 buggy? Also, dark theme is missing. and Settings item menu can't be clicked.

Same thing with 3.14.1 and Ubuntu 24.04.

Same thing with 3.14.3, requesting authentication at each logon, Crash when you want to access the settings (debian 12 / mint 22)
