Can't open experiment from builder after syncing with Pavlovia

OS (e.g. Win10): WIN10
PsychoPy version (e.g. 1.84.x): 3.1.5
Standard Standalone? (y/n) Y
What are you trying to achieve?: Edit a protocol on builder after syncing with Pavlovia, my experiment has various code components writen in Python

**What did you try to make it work?:**I have tried to disconnect to pavlovia, tried to open from windows explorer and save with a different name, create a new directory

What specifically went wrong when you tried that?: Builder does not open the psyexp file, without any message

After searching a little bit more I got the following messages on coder output:
19.5415 WARNING Parameter ‘Audio latency priority’ is not known to this version of PsychoPy but has come from your experiment file (saved by a future version of PsychoPy?). This experiment may not run correctly in the current version.

I’ve solved it. I don’t know how, but looks like I had an issue with the version of Psychopy3, I’ve created in 2020.1.3 and changed to 3.1.5, unintentionally.
