System Information
Operating system: macOS 10.15.7 (19H114)
Graphics card: AMD Radeon Pro 5500M 8 GB graphics

Blender Version
Broken: 2.91.0 (2.91.0 2020-11-25)
Worked: N/A

Short description of error
I exported the attached .dae file from SceneKit on iOS. When I try to open it in Blender, it crashes. It's worth noting that Apple's documentation for the SceneKit → .dae export says it should work only on macOS, but I was able to use it on the iOS simulator. It's possible that I'm using some sort of unsupported configuration, but Blender should at least report an error instead of crashing. And if there's something wrong with the .dae file, I'd like to report it to Apple.

Exact steps for others to reproduce the error

Open Blender.
Choose File → Import → Collada (Default) (.dae).
Choose the attached Juggler.dae file.
Try to import with default options: all checkboxes are Unchecked under Import Data Options, Armature Options, and Keep Bind Info.
Crash.

I had a similar problem with an addon that uses collada for importing geometry on my Windows 10 system. Works with 2.83 though, haven't tried 2.90. I thought the addon was broken, but it looks like it's a Blender thing.

This crash appears to be caused by a null pointer dereference inside OpenCOLLADA, the backtrace is the same as the one referenced in https://github.com/KhronosGroup/OpenCOLLADA/issues/643. OpenCOLLADA proper has been inactive since 2018 though.
