Activities Freeze

Hello friends
I am a new user of the manjaro distro, and previously used ubuntu.
Of the many distros that have been tried, the choice in manjaro is one of the best choices at this time. but now i have problems when using manjaro, sometimes the system freezes. especially when I open several applications, but when I want to open the second application suddenly the system freezes. all i can do is just close the application window.
the following screen when the system is frozen.
and all I did was restart the laptop.
this is sometimes very useful, when I’m working on a spreadSheets application and can’t save the document I’m working on.
as a result I have to repeat the work I was doing.
As for the specifications that I use:

OS: Manjaro Linux x86_64

Carnel: 5.10.42-1-MANJARO
Uptime: 10 mins
Packages: 1171 (pacman), 7 (snap)
Shell: bash 5.1.8
Resolution: 1366x768
WM: Mutter
WM Theme: Matcha-dark-sea

Terminal: gnome-terminal

I don’t have the same issue as am using Manjaro i3wm and Nvidia 465.31
Please provide the output to the command ‘inxi -G’ and ‘pacman -Q | grep mutter’ out of interest as could be a window manager bug
