question: [20381:0621/222132.072286:FATAL:setuid_sandbox_host.cc(157)] The SUID sandbox helper binary was found, but is not configured correctly. Rather than run without sandboxing I'm aborting now. You need to make sure that /tmp/.mount_BitwaruTOYo3/chrome-sandbox is owned by root and has mode 4755.
