there are a few ways to disable the splash screen when opening Opera One:
Method 1: Using Opera Settings:
Open Opera One and click on the Opera menu button (the red "O" icon in the top-left corner).
Go to "Settings" and scroll down to the "Advanced" section.
Under "Advanced", click on "System" in the sidebar.
In the "Startup and Shutdown" section, toggle off the "Show splash screen on startup" option[1].
Method 2: Renaming or Deleting Splash Screen Files:
You can try renaming or deleting the splash screen files to disable it.
Find the Opera installation directory on your computer (usually located in "C:\Program Files\Opera").
Look for a file named "opera_gx_splash.exe" or similar, and either rename it to something else or delete it[2].
Please note that modifying or deleting system files can have unintended consequences, so proceed with caution and make sure to backup any important data before making any changes.
I hope this helps! Let me know if you have any further questions.
