### Reproduction Steps

Occurs in application Ability Drive v 2304.0.0.6 (see https://tolttechnologies.com/alpha for MSI download, matching symbols at https://tolttech-bits.s3.us-west-2.amazonaws.com/abilitydrive/ToltTech.AbilityDrive-Symbols-x86-Release-2304.0.0.6.zip) when running on a Microsoft Surface / Win11 based Speech Generating Device from EyeGaze.Com. Have not seen a repro on other Windows based devices, this repro occurred twice in two days of testing over about 5 hours of usage, so failure frequency is uncomfortably high.

### Expected behavior

No ANE

### Actual behavior

Failure observed in crash handler twice in two days of testing, roughly five hours of runtime.

### Regression?

_No response_

### Known Workarounds

_No response_

### Impact

Unexpected halt of app, unable to establish a catch handler as it's in the WPF internals and callstack does not bubble up to app code

### Configuration

.NET Framework 4.8 (actual framework is 4.8.1) Release 533320
Running on Windows 11 22H2 Build 22621.1555
On Surface Pro 7+ Model 1960 i5 with Bios ver 18.200.143 and 8 GB RAM

Not sure if it repros any more or less frequently on other Windows variations at this time.
