Getting Error when trying to Update my Game

Hello,

Whenever I try to upload a new update for my existing game "Itzy Bitzy" I get an number of error messages:
When I click the create executable with the target set to GX.games / GMS2 VM / Default / Default, I get an error when it tries to synchronize with Opera GX.
It gives a message that says: "GXC synchronize failed" and a pop up that says: "Incorrect data. Check the output."
This is in the Output log:
Synchronizing with Opera GX...
Starting Sign-In to Opera
Refreshing OAuth2 Token...
