VBE7.dll crash when macro opens another workbook

[RockandGrohl]

Getting a really frustrating crash, which is happening -every- time a macro opens another workbook.

The workbook hasn't changed in name, type or anything since yesterday when it was working.

It was working yesterday, Tuesday, Monday, all last week and every day before that. Today, it crashes my excel when the macro goes to open this workbook using the following code:

If ahopen <> True ThenApplication.DisplayAlerts = False
[B]Set ah = Workbooks.Open("\\chw-dc03\company\Sales\Regional Press Selections\" & wbyr & "\Automation Hub.xlsm", False, False)[/B]
Application.DisplayAlerts = True
Else
ah.Activate
End If

On the bolded line, it immediately crashes my excel when it is ran.

Anyone got any ideas? Thanks.

EDIT:

This workbook itself crashes when I open it from Windows Explorer. VBE7.dll

This is actually a problem that happens periodically on different workbooks that have Macros in them, we have to restore from a backup file to get them to work again.

Here is an absolutely ridiculous fix. It doesn't solve the root problem, but it does fix the broken file:

1. Disable macros via, Options > Trust Center > Trust Center Settings > Macro Settings > Disable all Macros
2. Open problematic spreadsheet. Ignore message to enable Macros
3. Add a new Worksheet to the spreadsheet, save and then close spreadsheet.
4. Enable macros via, Options > Trust Center > Trust Center Settings > Macro Settings > Enable all Macros
5. Open problematic spreadsheet
6. Execute macro to test

Honestly, I find this completely ridiculous. The file is so broken it cannot be opened with Macros enabled. I tried everything else, new updates from August 2018 to Excel, regedit changes etc, none worked. I did this and it worked. I can't explain it.
