Excel VBA Print adds new line - excel

Question

Months ago I wrote a small Makro for my Company and until now it worked just fine.
Recently (maybe because we updated Office Version) there is a bug, that excel adds a new line in a print statement.
Code:
outputString = value1 & " " & value2 & " " & value3 & " " & value4 & " " & value5 & " " & user & " " & date
used to give me this output:
22 S ***/***s 9932256 B*****t Fatma 811 R******r Alexander 27.12.2019
now gives me this output:
22 S ***/***s 9932256 B*****t Fatma 811 R******r Alexander
27.12.2019
As you can see, excel adds a newline.
Can somebody tell me what happends here?
EDIT:
Solution:
Excel adds the new line after using:
user = Application.UserName
Maybe this is due to the office update we had. So I just took substring and cut the last character and works fine now.

Answer 1

Application.Username returns as the documentation states the username. As it is Read/write it can indeed happen that you will get a username that contains a vbLf or vbCrLf. Have a look at the following example
Sub UserName_VbCrlf()
Dim origUser As String
Dim user As String
' Be careful when testing as it replaces your username!!
' Maybe you save it first
origUser = Application.UserName
Application.UserName = "Storax" & vbLf & "Home adress"
user = Application.UserName
' This will give different lengths
Debug.Print Len(user), Len(Replace(user, vbLf, ""))
' Restore original username
Application.UserName = origUser
End Sub
