Hi @Robin Ganderton,
Thank you for posting your question on Microsoft Q&A Community. We're happy to help you with your concern.
To help troubleshoot the issue more effectively, could you please clarify a few details?
1/ Are you using Office Scripts or VBA macros? And is this happening in Excel for the web only, or also in the desktop version?
2/ Are the scripts triggered by buttons in the workbook, or are they run manually from the Automate tab?
3/ Do you see any error messages or logs when the script fails to run, or does it just hang on “Setting up to run”?
4/ Have there been any recent changes to the workbook, script, or your Microsoft 365 environment (e.g., updates, permissions, file location)?
5/ Are you able to open and edit the script in the Code Editor, or is that also unresponsive?
6/ Is the file stored in OneDrive, SharePoint, or another location?
Once we have more context, we can better pinpoint whether this is a script issue, a platform issue, or something else.
Looking forward to your reply.
