Hi Huka,
Based on your description, did you get the problem as shown in the following picture:

Did links still update in your environment? Did you get any wrong values?
In my opinion there may be some problems in the source, #REF! errors, missing links to macros, or links in the source that are themselves broken.
First please check the data source in your environment.
Then you can also refer to this KB article to get more information:

Any updates please let me know and I'm glad to help you.
