Mount Disappears

Big Sur 11.2.3, M1 Mac Mini, Cryptomator 1.5.13 (dmg-2755.123), MacFUSE 4.1.0. Most recent log is at the bottom.

When I unlock a vault, a Finder window opens and I can see the contents, and an icon appears that acts like a network drive. Yay.

Two issues.

First: An icon for the network mount does not appear in Locations in Finder. I would like this to happen like it does for my USB drive and my SMB mount. I have dragged the mount icon over to the Locations bar, but when the second problem happens, the shortcut becomes useless.

Second, way more important: After a few minutes, the Finder window for the vault closes, the drive icon disappears, but while Cryptomator reports that the vault is open, the reveal button doesn’t work and I am unable to reach the vault at all. The only way to make it visible again is to lock and reopen the vault. Lather, rinse, repeat. All I have to do to make this behavior happen is let it sit there.

Other: The vault is stored in a Dropbox. I’m still in the middle of the first giant data dump upload (~300 gig), which is being managed by a Linux machine. It will probably take another two weeks to complete, so I’m aware that not all my files will be visible until the sync actually finishes, but in the meantime I would like to believe that an on-going sync would not cause a crash-like behavior.

Any insight is appreciated.

ETA: When the vault closes in Finder as with item 2 above, it also is unmounted from /Volumes.
