Hi @Accounting
Could you please tell us which version of Office are you using?
What's the file format of your workbook?
Is there any software encrypts the HDD(SSD)?
- I suggest you open this workbook on other computers for a check.
Via searching online, you may go to Excel, click File > Options > Data > Data Options, uncheck the box of "Prefer the Excel Data Model when creating PivotTables, QueryTables, and Data Connections."
Besides, please try to right-click the sheet tab > Move or Copy > Choose a new workbook, tick the box of "Create a Copy" > Click OK.
