This issue has been moved from a ticket on Developer Community.

[regression] [worked-in:Community Preview 16.2.0 (untested)]
What steps will reproduce the problem?
1.Create a structure
Structure MyStruct
Dim A As Integer
Dim B As Integer
Dim C As Integer
End Structure
and create an array
Private MyArr(9, 3, 11) As MyStruct
2.
Trying to assign values
Dim n, p, r As Integer
For n = 0 To 9
For p = 0 To 3
For r = 0 To 11
With MyArr(n, error)
. A = n
. B = p
. C = r
End With
Next
Next
Next
3.
As soon as I try to write , p (after (n)) VS crashes
4.
The same problem apears in VS Community 16.2.4
Apparently this happens after upgrading both versions
Forcing the introdution (commenting the line, for example) and writing (n, p, r) and uncommenting the line, no error apears and the project is created

I have detected that for the last 35 days, this issue didn't have any product team activity and a very small amount of new votes or comments. Based on this, its severity, and affected area, it’s my experience that this issue is very unlikely to be fixed.

Thank you for taking the time to log this issue! Verified on VS2019 build 16.8.2, we create a VB winform project with the code:

Public Class Form1
Structure MyStruct
Dim A As Integer

    Dim B As Integer
Dim C As Integer

End Structure
Private MyArr(9, 3, 11) As MyStruct
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load

Dim n, p, r As Integer

For n = 0 To 9

For p = 0 To 3

For r = 0 To 11

With MyArr(n, p, r)

.A = n

.B = p

.C = r

End With

Next

Next

Next

End Sub

End Class

When We write p after n, VS not crashed, and popup two errors bellow the menu bar:
“IntroduceVariableCodeRefactoringProvider” encountered an error has been disabled.
“VisualBasicAddAwaitCodeRefactoringProvider” encountered an error and has been disabled.
Could you please have a try with the latest build, thank you.
