Can you help us solve crashes in DataGrid WPF?

Question

We are experiencing crashes in particular environments on customer sites in our WPF application.

• The callstack points to the DataGrid control, which contains in these cases CheckBoxes which are ToggleButtons (callstack).
  • Our codebase extends the DataGrid control but has been untouched since 2016
• For some users of a particular customer this reproduces instantly and for others sometimes. Internally we don't have a repro nor do other customers crash.
• We don't formally support Automation in our WPF application but these customers may use Automation on their system nonetheless.

I've searched around and I found very similair callstacks originating from other controls than ToggleButton. From what I understand have these been fixed in .NET updates:

• https://developercommunity.visualstudio.com/t/vs-1602-crashes-opening-naming-style-window/546969
• https://github.com/dotnet/wpf/issues/4279#issuecomment-1068216694
  • I've also tried the workaround mentioned in the latter link, but to no avail.
