[MC-149681] Server refuses to load overworld

So I run a private server for me and my friend to play on, and it ran fine on 1.13, but after the update to 1.14 I figure I update both the map and the world. SO I pulled the world save into single player to update, of course I backed it up. Downloded the 1.14 server file from minecraft.net and diid the normal. agree to teh eula, replaced the old server files and returned the world I had back into the sever folder. Even updated the server notepad so my friend can join.
However Whenever I try to start the server, I get a few errors and it proceed to load the overworld for god knows how long, before I have to take the task manager to the server to shut it down.
below are the two recent files from the server log. as well a screenshot of the server running before it goes into unlimited time loading the overworld.
edit add on: I will note that I play this server vanilla, without mod. But I do play with a texturepack.
