Whenever I boot my computer this error prompt and it says to delete or don't delete brisk menu, this is really annoying in my ubuntu mate 20.04.
reinstall applet works for me:
sudo apt-get remove --purge mate-applet-brisk-menu
sudo apt-get install mate-applet-brisk-menu
No still it didn't worked for me but thanks for the help.
Ok, try now:
sudo apt install --reinstall mate-applet-brisk-menu
sudo service lightdm restart
