Okay, then you have an object (or three) that has to be found and fixed.
The error message indicates that the definition for some of the Text in a Table is bad, so I'm assuming you created a Table.
I don't have any experience with Tables. I inserted a blank one, but didn't find anything about scaling text (although there was a Size entry).
Set to Selection Info under the View menu and click on the Table in your drawing. At the right, expand the Table Style entry and the Data, Header & Title entries under it. Check if the Test Height values are outside the range of 0.01 to 100.
