protection

For this we create a macro. To do this, call the development environment with the key combination ALT + F11 and insert a new module.

Now paste the following code:
Sub Remove_sheet_protection ()
On Error Resume Next
For i = 65 To 66
For j = 65 To 66
For k = 65 To 66
For l = 65 To 66
For m = 65 To 66
For n = 65 To 66
For o = 65 To 66
For p = 65 To 66
For q = 65 To 66
For r = 65 To 66
For s = 65 To 66
For t = 32 To 126

ActiveSheet.Unprotect Chr(i) & Chr(j) & Chr(k) & Chr(l) & Chr(m) & _
Chr(n) & Chr(o) & Chr(p) & Chr(q) & Chr(r) & Chr(s) & Chr(t)

Next t
Next s
Next r
Next q
Next p
Next o
Next n
Next m
Next l
Next k
Next j
Next i
MsgBox " The Protection sheet has been removed "
End Sub

Now run the macro with the F5 key. A message appears in a few seconds that the blade guard has been removed successfully.

Legal notice: If it is not your own worksheet and it is a matter of legal ownership then this code may not be used. Any use of this code is at your own risk.

I would be happy to find out if I could help.
