Why is System.Runtime.InteropServices.SEHException thrown?

Question

.NET

In a nutshell, this is the point. I have a program written in C#. It worked without failures for quite a long time, but recently everything has changed and now it often crashes throwing the aforementioned exception, while the input parameters do not change. There is no way to reproduce the error with the debugger. Presumably occurs when generating WPF forms.
Here is the error stack if it helps anyone:

Help me, friends! I've been drying my brain for a week now...

but it's better to show a piece of code where the exception comes from
