Intermittent crash during auto-analysis after loading an image using the DSC plugin

Version and Platform (required):

• Binary Ninja Version: 4.3.7094-dev (0f9d9b3f)
• OS: macOS
• OS Version: 15.2
• CPU Architecture: M1

Bug Description:
A NULL pointer dereference (it would seem) is occurring during auto-analysis that is triggered when loading an image in the DSC. It doesn't seem to matter to much which image.

Steps To Reproduce:

1. Load a copy of the DYLD Shared Cache in Binary Ninja.
2. Wait for libsystem_c.dylib to finish loading and for auto-analysis to complete.
3. Load the Foundation image.

I can only reproduce it when I have my plugin running which has some function workflow activities. It seems to happen 100% of the time when I follow the steps above. I'll see if I can figure out what function workflow work is being done that causes the crash if needs be.

Screenshots/Video Recording:
The following backtrace is where the crash occurs. This is on a function workflow advanced analysis thread.

Additional Information:
Starting happening on more recent dev versions - probably at least 4.3.7060, but couldn't be 100% sure. It may actually be do with some changes I made to my own plugin rather than a Binary Ninja version.
