Cannot Play the Ranked Mode (Mostly Ranked But sometimes Pubs)

Ive been Playing on Nintendo Switch since season 18. Recently since around season 23 The game has been Making it where whenever I join a ranked match It will Freeze as soon as I Join the match. Which I have to proceed to try and close the game. It will take a while and crash the game. Then I open it try to get back in and it makes me abandon or Redo the same process.

This is the tiktok I made showing exactly what happens each time in the ranked matches. And sometimes it even gives abandon penalty.
