Subdividision and Remesh Modifier freezing and crashing Blender

I cannot use these two modifiers anymore, because Blender will always freeze or crash, no matter how small the model is that uses a modifier. With remesh modifier my RAM shoots up to 100% (I have 64 GB) and therefore the program crashes sooner or later. What am I doing wrong?

Even on Suzanne ???

You may have to elaborate this to get a more suited answer.

  1. Initialize the scale of the object
  2. Increasing the amount of mesh little by little at an appropriate rate

※ The use of modifiers is affected by scale and rotation.
Initialization of scale/rotation is required before using modifiers.

Allocating large amounts of mesh at once leads to collisions.
(Use just the right or necessary amount of mesh. The amount of high mesh does not necessarily produce good results.)

Maybe your doing nothing wrong, but its hard to say. Post a screenshot what you’re doing, are there other modifiers used aswell, what blender version, what OS, do you use actual graphics drivers.
Sometimes a config breaks or a specific blendfile or a change does no longer work well in combination with addons.

So try it with again with default meshes like a uv sphere in a new created blendfile.
Try out another blender version, like a current daily build.
Deactivate all addons testwise.
If all fails try a new clean config and see if crashes there aswell.
