The operation Checked cannot accept the arguments: , [empty-string]
Note: You will not see another error reported for 5 seconds.

When you first initialize the app, the TinyDataBase doesn’t know all the tags you put. It will therefore put the value of “value If tag not here” the Switch cannot accept a value in the form of a string. You should put this kind of blocks:
blocks (1)
Set value of all your Tiny DB component if tag not here to : true or false
