Feature or Bug?

So, none of the models in my project can be displayed or if I drop anything from eCatalog that didn’t work. I checked the Cell Graph but there is nothing can be found, and I also checked the “show hidden components”. The size of the file is ~10 mb. The flow can be seen, and the products are there. I attached two screenshot.
Please help me.

Sounds like your layout is corrupted. Contact VC support, maybe they can help.

I had it earlier.
It is a known bug in VC4.3.0 and solved in 4.3.1
