Failed to create a ProcessSingleton for your profile directory

A Former User

Hello.
I receive this error when i run opera.

$ opera
[2775:2775:0826/084701.022745:ERROR:sandbox_linux.cc(368)] InitializeSandbox() called with multiple threads in process gpu-process.

This means that running multiple instances would start multiple browser processes rather than opening a new window in the existing process. Aborting now to avoid profile corruption.

Is it possible to overcome this?

$ opera --version
62.0.3331.116
$ uname -r
5.2.9-arch1-1-ARCH

I have symlinked opera configs and cache folders to cifs mount point instead of home.

$ cat /etc/fstab
//192.168.1.1/hidden /media/smb/hidden cifs nofail,noauto,x-systemd.automount,x-systemd.requires=network-online.target,x-systemd.device-timeout=5,credentials=/etc/samba/.smbcredentials,uid=1000,gid=985,forceuid,forcegid,vers=2.0,iocharset=utf8 0 0

$ ls -la ../.cache/opera
lrwxrwxrwx 1 login users 46 Aug 26 08:47 ../.cache/opera -> /media/smb/hidden/arch_home_const/.cache/opera

$ ls -la ../.config/opera
lrwxrwxrwx 1 login users 46 Aug 26 08:47 ../.config/opera -> /media/smb/hidden/arch_home_const/.config/opera

Checking for these files in working browser i found out that it makes another symlinks:

$ ls -la opera/
lrwxrwxrwx  1 login users      19 Aug 26 09:03  SingletonCookie -> 5384071957362275603
lrwxrwxrwx  1 login users      17 Aug 26 09:03  SingletonLock -> fallback-os-13855
