Crash in Welcome Onboarding

I found that crash in GPS in 1.48.160. We need to fix and uplift to a stable channel.

Going to label this as QA/No as this will get checked by default when we're running through the reduced manual passes for the 1.48.x maintenance release. CCing @Uni-verse @srirambv just in case to keep an eye when running through onboarding when launching Brave for the first time when 1.48.x RC builds come available.
