No Data Recorded?

If this template helps then use it. If not then just delete and start from scratch.

OS WIN 10
PsychoPy version 3.0.7
Standard Standalone? YES

For some reasons, my data didn’t save even without any notification of being crashed. I could not see any files saved except for the Text Document file. Is there any way to retrieve the data? This is the first time it happened; I have been running the experiment for around 2 weeks, but nothing like this happened before.

There isn’t enough information here for us to know what’s gone wrong. Usually when data aren’t saved it’s because the user presses the stop button (red cross) or, in some past versions, because they didn’t have any loops in the study.
Maybe look carefully about what has changed in your study recently

I did not modify the experiment at all, so I am not sure what happened. The experiment ended normally, but when I check, data was not saved at all~
