I created and played on this world for 27.2 hours. The problem started when I started out trying to add mods to my game. It seems that the mods seem to have affected my saves. I know that this issue is due to modifications is because worlds that have been created after this issue work perfectly fine. This problem is on Minecraft: Java Edition 1.21. I added several attachments below that should explain my problem. Pleas email me if you have any further questions. I sincerely appreciate your help. 

Best of luck, Ansonlolhi.
