This error did not show for 1 year. Also checked the power query there is no such problem in the conversion to Number.

Then maybe the data changed and now you got a value that contains text and can't be converted to a number. Check all of the entries in the data source.

Also in the future add more information, with only an error message it's hard to help you.
