You could rename your existing Studio One folder and download a fresh install.
Something has corrupted your install.
Do that or call Support.

I've just uninstalled and installed again S1 and the issue continues. I will contact support, but I guess that my deadline just went out the window!

Go into Studio One -> Options -> Locations -> User Data and make sure that path is pointing to your song folder. That's the only thing I can think of, but I'm pretty new to S1.

Thank u guys for your replies so far.
I am noticing that the problem is that the left click is not working on Studio One only. I try to click on a track it won't let me, I try to click on the start marker it won't let me either. However, it will let me click with the left mouse for dragging an instrument! This is so weird. Ahh forgot to mention, but while I was working I got a crash error saying that something made S1 crash unexpectedly and a crash error was filled somewhere. Can't find that anymore since I uninstalled the software.
Ps. I already filled a ticked. Thanks in advance for any further replies

Did a video for the tech support guys!

Have you tried selecting a different tool? It looks like you're trying to work with the audio bend tool selected. Does the behavior change if you select a different tool?
