When moving with move_and_slide, a Capsule CharacterBody3D collided against StaticBody3D bodies with BoxShape3D shapes, gets stuck and jitters

Windows 10

Issue description

Capsule CharacterBody3D moving with move_and_slide gets stuck between a StaticBody3D with 2x BoxShape3D and keep jittering excessively when trying to move:

CharacterStuck3D.mp4

Trying to move away:

CharacterStuck3D2.mp4

Other issues

This is different from #75399 and #70453 as those ones are related to Convex Hulls stutters and ConcavePolygonShape3D stuck.

Collision setup

Steps to reproduce

• Add a StaticBody3D and 2 BoxShape3D close to one another
• Move with a Capsule CharacterBody3D move_and_slide against the StaticBody3D
• Character will get stuck and jittering in place

Minimal reproduction project

Run project and move forward against the ramp, then hold W to keep moving forward or try to get out of the stuck geometry.

• CharacterBody3D jitters against static bodies, gets worse the bigger the collision shapes are and the farther away from the world origin/CharacterBody3D they are. #75537 - but I'm not sure mine is a duplicate, since mine is related to small BoxShapes close to one another. That one is getting stuck in a big wall.

I think this is basically this: #72988, it's also the same issues as i have which alfred linked above,

[alfredbaudisch]

@viksl my report is when colliding with StaticBody3D the one you linked with RigidBody3D. So both are worth keeping and validating.

[viksl]

@alfredbaudisch Yeah, but it happens with any body, static, rigid, character all of them display the same issue it seems so far.

this also occurs when interacting two 2d sprites using move_and_slide

Hi, I started with official tutorial (make first 3d game) and yes, I stuck with my character (CapsuleShape) in collision with rigidBody (CylinderShape), in certain part of cylinder with certain scale of cylinder and capsule. Then if I am stuck, then I cannot go even directly from that object or sometimes I stuck completely in any direction. It is also in collision with CubeShape. I am using move_and_slide
