When I trade with a cartographer Villager and he levels up to level three, he will freeze and cause the game to also freeze. The only way to fix it is to go into task manager and end Minecraft altogether. Then when I go back into the world it sets me back a bit because I couldn't save.

OptiFine mod problem. Caused by reaching levels 2-3 of Cartographer trading that has Ocean/Woodland Explorer maps. The freeze does not happen in vanilla, even when continually spawning and leveling Cartographers up to generate those map trades; just only minor server lag.
Cartographers freezing world. · Issue #6001 · sp614x/optifine · GitHub
I'm pretty sure if you wait for about half an hour the game will save so if you have made a lot of progress you don't want to lose you might want to wait
Thank you for your report!
However, this issue is Invalid.
Your game, launcher or server is modified.
If you can reproduce the issue in a vanilla environment, please recreate the issue.
Any non-standard client/server/launcher build needs to be taken up with the appropriate team, not Mojang.
Any plugin issues need to be addressed to the creator of the plugin or resource pack.
If you have problems on large servers, such as The Hive and Hypixel, please contact them first as they run modified server software.
