Fusion crashing on component selection

Hi, I'm having trouble with a design. This design consists of two components. When I open the design and move the mouse cursor over the first component, it should display its shadow in 3D. However, Fusion stops responding, and I have to close the software. It's quite frustrating to work with because this component is part of an assembly, and every time I need to move it, Fusion crashes. I discovered the latest version of the design where this issue doesn't occur, and the difference with the next version, where the problem arises, is the modification of the height of a referenced sketch on the origin plane.

I marked the component and the sketch that are causing the issue. On the right, I also highlighted some features that, if deleted, will also cause the problem.

You will need to attach your model.  Open the model in Fusion 360, select the File menu, then Export and save as a F3D or F3Z file to your hard drive. Then use the Attachments section, of a forum post, to attach it.

I'm sorry, you will find the model attached to this message.

I see no issue with your model except for a few timeline problems, mainly with missing profiles.  I can mover it around, edit it in various features without issue.  You may want to lighten the model up by Removing the sub-assembly the model came from by right clicking on it in the Browser and choose Remove from the context menu. The model after this operation is attached.

Thanks for the model, @vinicius.strini - I found that the first time I selected "Component1", it was, indeed a bit slow.  But, it did not crash.  Selection took about 30 seconds.  Then, after that, I was able to select that component very quickly.  We will investigate this, but Fusion is not crashing.

 

One tip:  Turn off "Show default measure".  This tries to compute a lot of stuff about the selection, and can be slow:

I'm starting to believe that it's my computer. Is there any configuration that I could change? None of the suggested solutions worked. Here is an image showing the state it gets into:

It's not a definite crash, but I left it in this state where the CPU usage stays at 100% for about 1 hour, and the program doesn't respond. My hardware specifications are as follows:

Processor: Intel I7-10750H

RAM: 32GB dual channel 3200MHz

GPU: NVidia RTX 2070 Q-Max Design 8GB



OBS: I noticed that if I make changes to the design without selecting the component directly first, the issue doesn't occur. For example, if I make changes to another sub-assembly first and then select the component, the problem doesn't happen.

interesting...  When I tried it again, I let it run for 10 mins or so, and it did not ever finish.  I have no idea what I did differently the last time, because it definitely was slow the first time, but then was fast on subsequent selections.

 

I also noticed that a Compute All after open seems to prevent the problem - another workaround to use.

 

I created bug FUS-130059 for this issue.

Thank you guys for the solutions provided and for opening the bug report!
I found a version of the design that doesn't have the issue and worked on it until reaching the final design, and the problem stopped occurring. The difference is that I didn't remove any features like I did in the version that started causing the problem. I will close the topic.

Best regards
