finder sync no longer working, which has happened before and was fixed before too (thanks for that!)

[ifjuly]

the finder sync option no longer working, which has happened before out of the blue and was eventually fixed by notifying. error message upon trying to load it every time 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."
