App crashes on launch in 1 qube, but not another?

I’ve run into this a few times, and can’t figure it out.
I have 2 qubes sharing the same template. In 1 qube the app opens fine. In the other it crashes on launch.

I can imagine that it could be a memory issue, but both have the same memory params.

What else might be going on?

Separate template makes a huge difference

You can try to clone those qubes to confirm that it’s not due to RAM. Then, you can create a fresh qube from that template and try to run the app there.
