Crashing Error on Saving

[WindowGuy]

Hello,
I am experiencing a major issue with my excel no longer saving. My file is running my business and this is a series issue for me i do not know what to do?
I am still a beginner but i tried clearing temp files already on computer with %temp% in cmd. I also tried removing some checkmarks from boxes in trusted center.

Please help i am so lost.

It sounds like your file has become corrupted.

Your best bet would be to restore a copy of the file from a recent backup that occurred before the corruption issue.
Hopefully, you won't lose too much data changes that you have made from the time of the backup to now.

Other than that, you may want to have a look here: Repair a corrupted workbook - Microsoft Support

Last resort would be to hire someone who specializes in trying to save/fix corrupted Excel files.
You can look online to find services that do that.
