How did you install Magisk? I currently run stock OS with Magisk (though without any modules, was just curious after temporarily returning to stock) and do not experience any problems. Did the update to 25.2 just today.
If you didn’t choose @hirnsushi’s path and flashed the boot.img instead, maybe it’s worth a try. You would have to remove Magisk first and return to the original boot.img of course.
