Hmm... what are you trying to do on blender? or is it just crashing at startup?
Blender crashing on startup can be due to a lot of different issues such as insufficient system resources, outdated graphics drivers, or problems with Blender's files. I would recommend checking if your computer meets the requirements for blender and try updating your graphics drivers, you can also try deleting the startup.blend file to reset all of Blender's settings. Also try running Blender in factory startup mode.
OR it could be due to you running too much at the same time so try closing stuff you're not using and check for updates on your computer. Most of the time when it crash's for me is when I try making realistic water or liquid it also crash's when I try using gravity mixed with the wave effect on a plane idk hope this helps
