I'm having trouble with a Python script that I wrote to automate refreshing an Excel workbook, and it's causing Excel to crash. The script uses the win32com.client library to open Excel, refresh all data connections, and then save and close the workbook. However, after running the script, Excel crashes when I try to open the file again. I've checked, and Excel opens non-macro files and files without power queries fine, and I can open the problematic file in safe mode. I've also restarted my computer multiple times. I suspect that there might be a background process still refreshing the queries, and I'm not sure how to fix this issue. Has anyone else experienced something similar, or can anyone offer some suggestions?

If you're able to, use ctrl+shift+esc to bring up the task manager and make sure there are no lingering Excel processes. I would also recommend making the application visible during troubleshooting to catch any hidden prompts that could be causing the crashes.
I think you should try running Excel with it visible instead of hidden. This way, you might catch any prompts or dialog boxes that need your input, which could be causing the hang-up. Also, consider separating your operations – open, refresh, save, and close – and use try-except blocks to handle exceptions. This might prevent crashes and help you determine where things are going wrong.
Have you tried rebooting your computer? Sometimes that can solve strange issues. However, it sounds like the file might have gotten corrupted in your process, especially if it's crashing even when opened manually.
