I was having the same issue. I have applied the following solutions to two different PC using Windows 11 and it has fixed crashing issues. Not sure why it works but I was trying everything possible until I found a solution.
FIX: -Run your Grounded and select the graphics setting you desire but turn off V-Sync and Chromatic Aberration. Apply config and quit the game.
-Open the config folder for the game Xbox install located: C:\Users\XXXXXX\Appdata\Local\Maine\Saved\Config\WinGDK\GameUserSettings.ini with notepad or notepad++
-Top of config file;
sg.ResolutionQuality=100.000000
sg.ViewDistanceQuality=3
sg.AntiAliasingQuality=0
sg.ShadowQuality=3
sg.PostProcessQuality=0
sg.TextureQuality=3
sg.EffectsQuality=3
sg.FoliageQuality=3
sg.ShadingQuality=3
-Set "sg.AntiAliasingQuality=0" and "sg.PostProcessQuality=0" both to 0 and save the config file
-If you make any changes to your display settings after doing this you will have to go back into file and change to 0 again.
I have no idea why this works but I have had no crashes since doing this on both machines. This also removes the blur effect for the distance and allows you to see a lot further (added bonus).
I hope this fixes your issues.
