So when using MacOS my MacBook instantly shuts down. For example i just open Final Cut Pro and it instantly turns off. I was later filling a form in Google Chrome and it instanlty shut down in the middle of that process too. Battery at 50%

I tried using windows bootcamp and for the first 20 minutes it seems okay and no shutdowns

Any idea/fix/recommendation
Greatly appreciated
Thanks in advance
I have also tried resetting the SMC as well as reinstalling mac os here is a of what happens when opening something like Final Cut Pro or Chrome

Does the bottom of the machine feel warm/hot? Has MacBook ever been opened? I'd venture to assume dust has overtaken inside and it's over heating.
