If the function call in the screen starts "blocks is causing the problem, then, perhaps, broken the procedure for obtaining the data and you try to work with data that is not yet loaded into the application. You need to find a unit that causes the failure. Error creates not function, and the blocks within it ---

As you know, update Thunkable X occurs in the background and at the same time can make a break. To check the integrity of the application required system tests, but Thunkable X there are no mechanisms to create the necessary tests, with which you can fully test the functionality of the new assembly. Each tool for mobile application development has its own characteristics, purpose and scope. You have been working with Thunkable X and I think that you understand the characteristics, purpose and scope Thunkable X. ---

In particular, the error is related to the use of the `rownumberacil` variable. Take a look at how that variable is used. If you want more help from us, please post a copy/share link to your project (or ideally a simpler project showing the same behavior). FWIW, it appears as if it is related to the Local Storage component because the current implementation of app variables uses the same underlying capabilities (i.e. AsyncLocalStorage) as the Local Storage component (note that this implementation will likely change soon). -Mark ---
