Submitted #175 to resolve the Unity issue.

[SimonDarksideJ]

Need to retest once the latest version is up to ensure the bug is resolved.

[StephenHodgson]

I had, but I'll let you close it once you've validated :)

[SimonDarksideJ]

Still crashing in 1.11 :S

[StephenHodgson]

I cannot reproduce this with your steps. Is there something else I'm missing?

[SimonDarksideJ]

Appears to be a deep routed Unity bug, will have to provide documentation to workaround it for now.
#183

[StephenHodgson]

@SimonDarksideJ do you have a case number for tracking purposes?

[StephenHodgson]

Any update to this?

I know we've narrowed it down to the SDK package specifically using the default configuration profile.

[StephenHodgson]

I saw you opened a new bug report on this: https://fogbugz.unity3d.com/default.asp?1184509_lkg3v0pa94vntobc

[SimonDarksideJ]

Solved for GitHub based UPM implementation. But now that we have moved to a UPM server, it's back again....

[StephenHodgson]

Hasn't seemed to be fixed yet. Let's try adding a delay call to the Selection.activeObject on line 130

[StephenHodgson]

@SimonDarksideJ you confirmed this is fixed?

[SimonDarksideJ]

Confirmed, the crash fix does appear resolved. However, we are no longer receiving the prompt to configure the platform. (XR settings and IL2CPP)

[StephenHodgson]

Sounds like a new bug report to me.

[SimonDarksideJ]

I think I'm fine with that

[StephenHodgson]

This still happened for me with 2019.1.14 and xrtk core 0.1.21
