Check in Help > About to make sure you're actually using the 2025 version. The shortcut you're using to launch PT might be still loading the 32-bit version, which we no longer offer and would be a 2020 version at best.

The error in question means that PT is having trouble talking to your audio drivers - this could be due to running a 32-bit app with 64-bit Windows and drivers, or could be something else. What type of sound card/audio interface do you have? If you go to Options > Preferences > Audio, what driver type are you using?
