Bug Player Keeps Bouncing Off Corner of Platforms/Blocks PLEASE HELP

I have spent about 20 hours trying to fix this and tried just about everything at this point. I am using a Tilemap and using a Tilemap collider and and a composite Collider with it.
I have a Dash on my character and when it lands on the corner of the blocks/platforms the player bounces off and for some reason it doesn't detect a collision. I added a Physics Material with no friction and no bounce to just about everything and it still happens.

I tried to upload a gyf to gyfcat but it did not work so here is the link to the clip: https://clipchamp.com/watch/O6C9n3KWwpa

Here is the code for the movement:

Code (CSharp):

1.     void Update()
2.     {
3.         movementDir = Input.GetAxis("Horizontal");
4.         if (Input.GetKey("space") && isGrounded)
5.         {
6.             jump = true;
7.         }
8.         if (rb.velocity.y > 0f)
9.         {
10.             rb.gravityScale = 1.5f;
11.         }
12.         else if (rb.velocity.y < 0f)
13.         {
14.             rb.gravityScale = 2.5f;
15.         }
16.     }
17.  
18.     private void FixedUpdate()
19.     {
20.         movementHandler();
21.  
22.     }
23.  
24.     private void movementHandler()
25.     {
26.         if (!playerPowers.hasDashed)
27.         {
28.  
29.             rb.velocity = new Vector2(movementDir * speed * Time.deltaTime, rb.velocity.y);
30.             playervelocity = rb.velocity;
31.             if (movementDir > 0 && flag)
32.             {
33.                 playerTransform.Rotate(Vector3.up, 180f);
34.                 flag = false;
35.             }
36.             else if (movementDir < 0 && !flag)
37.             {
38.                 playerTransform.Rotate(Vector3.up, -180f);
39.                 flag = true;
40.             }
41.             if (jump)
42.             {
43.                 isGrounded = false;
44.                 jump = false;
45.                 Vector2 jumpVector = new Vector2(0f, jumpForce * Time.deltaTime);
46.                 rb.AddForce(jumpVector);
47.             }
48.         }
49.         else
50.         {
51.             rb.velocity = rb.velocity;
52.         }
53.  
54.     }

Here is the code for the collision detection:

Code (CSharp):

1.     private void OnTriggerStay2D(Collider2D collision)
2.     {
3.         if (collision.gameObject.tag == "Ground" && rb.velocity.y > -1f && rb.velocity.y < 1f)
4.         {
5.             playerMovement.isGrounded = true;
6.         }
7.     }
8.     private void OnTriggerEnter2D(Collider2D collision)
9.     {
10.         if (playerPowers.hasDashed)
11.         {
12.             Debug.Log("Collided");
13.         }
14.         if (collision.gameObject.tag == "Ground")
15.         {
16.             playerPowers.hasDashed = false;
17.         }
18.     }

Here is the code for the Dash:

Code (CSharp):

1.     // Update is called once per frame
2.     void Update()
3.     {
4.         checkDash();
5.     }
6.  
7.     private void FixedUpdate()
8.     {
9.         if (dash)
10.         {
11.             dashHandler();
12.         }
13.     }
14.  
15.     private void checkDash()
16.     {
17.         if (Input.GetKey("e") && !playerMovement.isGrounded && !hasDashed)
18.         {
19.             dash = true;
20.             hasDashed = true;
21.             stopMovement = true;
22.         }
23.         if (playerMovement.isGrounded)
24.         {
25.             hasDashed = false;
26.         }
27.  
28.         if (playerTransform.rotation.y == 1)
29.         {
30.             dashDirection = 1;
31.             dashRotation = 270f;
32.         }
33.         else
34.         {
35.             dashDirection = -1;
36.             dashRotation = 90f;
37.         }
38.     }
39.     private void dashHandler()
40.     {
41.         Vector3 dashLocationPos = new Vector3(dashLocation.position.x, dashLocation.position.y, 0f);
42.         Instantiate(dashAnimation, dashLocationPos, Quaternion.Euler(0f, 0f, dashRotation));
43.         rb.AddForce(new Vector2(dashForce * dashDirection * Time.deltaTime, rb.velocity.y + dashY *Time.deltaTime));
44.         dash = false;
45.     }

I have done just about everything for the collision detection including using raycasts and boxcasts but the issue persisted.

I have done collision handling in FixedUpdate and OnTriggerEnter and it still does it.

I also realized that when this happens the OnTriggerEnter function does not get called.

I made my dash in a way where if you dash, you won't be able to move hence why I have the if statement on my playerMovement script.

Please help me I'm reaching my limit.

 

This stuff is hard to get right, smooth, buttery, etc.

I think perhaps Unity supports some stuff like Compound Colliders but for that I will have to page @MelvMay as he has a repo with some cool examples of smooth 2D movement.

Otherwise, here was the oldskool way of getting buttery corners:
