#197 Veracrypt 1.21 | Force dismount network shared volume crashes my computer if network share no longer available

[Sakis A.]

This is a bug report. I am using Veracrypt 1.21 for macOS. The case is this:

• I mount a veracrypt volume that resides on a network drive which is shared via afp (it's in the internal HDD of a time capsule device)
• Everything works smoothly until I change WiFi (when I leave my place)
• The network share is apparently not available any more. Veracrypt shows the volume as still mounted.
• If I (force) dismount the volume through veracrypt, my whole computer crashes - something which should not happen under any circumstances.

I don't know if there are any log files that veracrypt keeps. I could post them here if needed.
