I would love to assist with this issue but have a few additional questions that could help me narrow down the root cause of the issue. As well as if this is still a prevailing issue preventing work, I would suggest opening a support case with our Support Team.
+ Is this an isolated issue?
+ Or is it all workbooks that are attempting to be opened and refreshed by the new 9.2.4 Tableau Desktop are experiencing this issue?
+ What type of data source are these extracts being ran on?
+ The extracts that are being updated are they extremely large? >100,000 rows of data?
+ Are you able to create the extract with the correct data at all?
