If you copy a cell or range - it should paste fine, but not simple text.
You can only PasteSpecial ranges with Transpose:=False.
To fix this, you can change MS Excel VBO, Paste, Paste Values code stage:
This line: range.PasteSpecial(Paste:=Paste_Option, Operation:=-4142, SkipBlanks:=False, Transpose:=False)
Change like this: range.PasteSpecial(Paste:=Paste_Option, Operation:=-4142)
Both SkipBlanks and Transpose are false by default anyway, so it should not change anything working now, but it will start working in some cases it failed before.
