UE4 4.26 Static mesh editor crash opening any static mesh

I have just started working with version 4.26, here is what happens I have created a new project with a blueprint and blank template settings, and added starter content.
Once the project loads, I simply click on the starter content folder props and select any prop such as the sm_chair to go to the static mesh editor at about 25% the editor crashes.
Thank you for any help with this.

It happens the same to me!

I fix up all redirectors, verified UE installation and delete “saved”, “intermediate” and “DerivedDataCache” folders.
it’s still crashing.

Here is an update on the issue from unreal for those having the same problem, It looks like it was fixed and will be released for version 4.27.
Thank you to all who fixed this problem.

This issue started occurring for me seemingly at random, after having opened the static mesh window many times without issue.
A work-around that worked for me was to reset the layout of the editor to the default, or one of the layouts I had stored earlier.

(e.g.: Window > Load Layout > Default Editor Layout)

After that, I could open the static mesh window again without crashing.

Can confirm this is related to layout. Had the same issue, no static mesh would load in whatever project. Suspiciously right/near when I changed my layout. Recall b/c I never do so and soon after I started crashing.

For sure I can confirm reloading the default layout immediately resolved the issue for me.

Worked for me on source build 4.26.2 on 2/17/22 Windows 10 with latest update. Thank you so much!

Dude. Thank you so very much. This means a lot to me. Thank you, really. I thought 6 months of work got corrupted beyond salvation.

Hi guys, I found another way around it → Clone the project.

I couldn’t open it anymore due to many different ways I tried. Cloned the project, opened the second one, loaded the default layout, saved, reopened the first one, did the same et voila.

Hope it can help someone in need.
