@esrakartal-xealth Can you please share the project that causes this?

@sandersn
Check for undefined globalObjectType in getPropertyOfObjectType
9256e11 
This can happen during symbol merging when initialising the checker,
because global types aren't set until after symbols are merged.

May stop the crashes in #47179, #47181, #47180.
Does not address the underlying problem of needing to resolve aliases,
and therefore names, during symbol merging when initialising the
checker.

If you having issue with this, just uninstall VSCode and install version 1.61.2. It will help till this problem is solved, aspecially if you are on development.
