App randomly (eventually) freezes after entering master password

[dfparent]

Overview

Sometimes after entering the master password after the PC has been asleep, the app freezes up and requires me to kill it using task manager. Once the app is restarted everything works normally for a while.

Steps to Reproduce

1. Open database in KeePass. Leave KeePass running.
2. After some time (perhaps several standby/sleep/hibernate cycles) when I go back into KeePass and enter the master password, the application freezes up and never unlocks. This happens whether I am using the Windows hello PIN or typing in the master password.
3. Use Task Manager to kill the KeePass process.
4. KeePass starts up and operates normally after that – until the next time it freezes, perhaps several days from now.
5. This happens dependably and fairly regularly, although unpredictably.

Expected Behavior

KeePass never locks up so bad that I have to kill it with task manager. This makes it a hard sell for my less technical family members.

Actual Behavior

See above.
