The exact error message is:

> We were unable to load KBFS (Fuse kext). This may be due to a limitation in MacOS where there aren't any device slots available. Device slots can be taken up by apps such as VMWare, VirtualBox, anti-virus programs, VPN programs and Intel HAXM.
>
> Please run `keybase log send` to report the error.
