Describe the bug

DWM appears to have a chance of crashing when bringing up a taskbar window preview. I believe it can also happen when the Virtual Desktops flyout appears, but I can't remember for sure.

To Reproduce

Just hover the mouse cursor over an open taskbar item and see if it crashes when the window preview appears. It's not consistent and happens at random.

Screenshots

Additional information (please complete the following information):

DWMBlurGlass version 2.3.0
Windows 11 24H2.26100.2454

What other third-party software do you use:

None

Additional context
It happens more often than I would like. OpenGlass has the same issue, so it must have been inherited from whatever code is in there (I've been meaning to file a bug report over there). I'd attach a dump file, but it appears to not make any when it crashes, as I don't see any in the program directory.

Here's my config file, in case maybe it's a setting I have enabled that's causing it:

applyglobal=true
extendBorder=false
reflection=true
oldBtnHeight=true
customAmount=true
crossFade=true
