Microsoft Excel freezes for every safe operation

I have a datasets in csv format which I always load onto excel. I do some manipulations of the data and filter out a few rows based on the results I obtain. Then I will plot the data and save it with the file name same as dataset name for further reference . This is common in my job and was able to do it easily. But recently after a windows updates, I don’t know whether it is related or not but still, whenever I click on the save button, it simply blurs itself for few seconds and saves. Sometimes this will take so long that I am forced to use task manager to kill that Excel and of course all my work.why is this happening? Is it related to any updates? Can I uninstall a few updates and try again?
