D5 crashes while opening a file

When loading some of my projects in D5 Render, the application crashes before the scene even opens. This issue occurs in several of my projects and has caused serious productivity losses.

I have concluded that the source of the problem is related to downloaded assets. When I remove the assets, the project opens normally; however, when I download and add the same asset again, the exact same issue reoccurs.

Interestingly, when I load the problematic asset into an empty scene, there is no issue at all. The crash only starts when this asset interacts with other elements in the scene such as lights, materials, effects, or other objects.

Every time I report this issue, I am asked to send project files and additional information. However, this is clearly not a problem unique to me. It is your responsibility to identify and resolve this issue, especially since it has been reported for a long time by many users.

I simply do not have the luxury of waiting. I pay a monthly subscription fee for this software, and it is not acceptable to experience this level of instability while being asked to act as a beta tester.

This is only one of several ongoing issues I have experienced with D5 Render. Instead of requesting files from individual users, please provide one of the solution paths that you should have already identified for this long-standing problem.
