High CPU usage Linux 5.0

I'd get high CPU usage, up to 100% on 1 core at a time (with the core switching every 1-2 seconds). It rendered the system unusable and a few minutes ago made everything unresponsive so I had to hard reboot.

Just to confirm this was keybase, I turned off all applications and killed any processes that wasnt needed by the OS, the problem still occurred.

Both kbfsfuse and keybase processes had high CPU usage.

Start by retrieving the logs associated with ID 31511a100ca0b04853edb61c and reviewing the Linux 5.0 behavior of the kbfsfuse and keybase processes. Reproduce the high CPU usage if possible, identify the responsible subsystem, and verify that the system remains responsive after the fix.
