Excel crashes on save or copy

[Mandark]

I have a 6 MB xlsm workbook with Power Query (17 queries) and no VBA. Everything used to work propertly for years.

I made some changes to the queries and worksheets yesterday and since then, when I try to save the workbook or press CTRL+C, the workbook crashes. No error message, no warning, nothing, it just closes (without saving). I have tried the same file on colleagues PC and it works properly without crashing.

So probably, something is wrong with my PC. I deleted the temporary files, restarted a couple of times, but the situation is still the same.

Any idea where the problem could be and how can I fix it?

I had to reinstall the Office to fix it.
