Windows KBFS with Dokan not working when booting up (but manual start working)

After installing keybase on my Windows 10 Pro (20H1 preview, slow ring, build no 19041.172) PC I figured out that if Keybase starts on startup, KBFS goes into an invalid state where the K: drive exists but is unaccessible. If I disable the startup entry and launch keybase manually after start up, the drive mounts ok (same happens if I reopen keybase if it opens at startup). I am guessing this is an issue with the way keybase handles KBFS by mounting it on start and doing it too early. Would it be possible to implement a delay?

Start by reproducing the Windows 10 startup path with KBFS and Dokan, then compare it with launching Keybase manually after boot. Trace when the K: drive is mounted during startup and identify whether delaying that work avoids the inaccessible state. Done means KBFS mounts accessibly when Keybase starts with Windows, without requiring a reopen.
