Putty crashing on Windows 10

Using a dynamic proxy in Putty, I was encountering an issue where Putty would crash in Windows 10.  I got an error in the Application event log:
Faulting application name: putty.exe, version: 0.63.0.0, time stamp: 0x52012e86
Faulting module name: putty.exe, version: 0.63.0.0, time stamp: 0x52012e86
Exception code: 0xc0000005
Fault offset: 0x0001846e
Faulting process id: 0x3f4
[snipped]

Also looking at the System event log, I saw a lot of these (Event ID 140, Source NTFS):
The system failed to flush data to the transaction log. Corruption may occur in VolumeId: ??, DeviceName: \Device\ImDisk0.
(The device has been removed.)

This turned out to be an issue with Veracrypt.  I had the entire system drive encrypted.  After decrypting it, the errors are gone and everything is working again (for now).  Also, the system is running on VMware ESXi 6.0.
