Hmm, that's odd. It's not even really listing an error, just saying that there is a bug and giving a bunch of plugins. While it's not the expected bug for running through a browser, I'll still suggest this link as the first possible solution.I can't open the game. When I try to open it on the web version it gives me this View attachment 2945198
If I try to start the Mac version it simply says it can't start as there are incomplete or missing files.

Let me know if this doesn't help. And also please let me know what browser you are attempting to run the game through with the web version as well. Another thing you could give a shot is a different browser, such a firefox. (Unless that's what you are already using.) As for the Mac version, if your OS version is 11 or later, it's simply not compatible for RPG Maker MV, as something Mac changed in their OS broke compatibility. If it is version 10 or earlier let me know and I can try and troubleshoot it.
