Whenever I load a project in Cubase, all of my levels are peaking and I’m trying to understand why 
I didn’t hit the play button or space bar so the music can start playing. It just does this on its own… See…
Wow, that looks bad. What instrument is it? Make sure the VSTi is up to date, please.
Do you use any Insert effects on the Channel?
No I don’t have any effects on the channel either or routed to a fx channel or anything. No matter what plugin I use, even the Cubase instruments still does that (plus I hear a pop sound when I had my headphones on)
Do you think it’s my interface? I have a Steinberg UR22mkII Recording Package
Do you think I should reinstall Cubase again on my computer?
Nevermind! Nevermind! 
When I looked under the “Audio Inserts” for both instrument tracks, look at what I’ve found…
I can’t even remember if I even added any insert effects on these channels or not 
thank you for helping me 
I’m glad it works to you now.
That, and if it doesn’t seem to help and you suspect a VST instrument or plugin is behaving erratically, it’s a good idea to create a new clean project file and add it there.
