Macbook pro keeps restarting

When you reinstall the system I hope you're actually doing a full erase and reformat. Simply reinstalling the OS may not resolve your issue. It's best to backup your important files and use Disk Utility in Apple's Internet Recovery to erase the disk. After reinstalling the OS I would recommend NOT to install any additional apps or plug-ins. Test it out for a couple of days without any additional software. If you are still experiencing the instant reboots then you will need to contact Apple Support to send it to them for inspection and repair. If you have success with the reformat then it's definitely a corrupt file/s that caused the issue. At that point it's best to install apps one by one so you can figure out which software is the problem.

I mentioned the Chrome extensions because there could be a corrupt file causing the reboots. Since you have a lot of stuff installed there is a very good chance you have a corrupt file/s.

What you can do is create a new user account. This will be free of the apps you have installed outside of Apple's built in apps. This way you can test it and see if it continues to reboot.

What you have installed on it besides the built-in Apple apps? What do you have connected to it? Are you using Chrome? Because it has a lot of extensions that people use for it and the can cause issues if they are not compatible with Catalina.

"And all what you are saying is so weird. Why i shouldn't install any additional apps? :D So what should i do with this laptop. look at it? :D "

At this point I'm going to let someone else chime in about your MacBook Pro issue if they care to. No one gets paid to help people here. This is a community-based forum and we are all Mac users. Every time I try to post to help you about your Mac situation you reply back with some passive aggressive response. Now you're saying my advice is weird? Okay dude. Good luck.

I did see the GPU panic in the log but I have to be honest I'm not at all proficient with crash logs. Hopefully someone else will chime in that understands them better. Best of luck!
