I recently did a factory reset on my computer and chose to remove everything, So I then reinstalled Minecraft: Windows 10 Edition and it was running smoothly for a couple of weeks and then when I played Minecraft again, I got an extremely large lag spike, It was clocking in at about 1-2 frames per second

This isn't supposed to happen on a high-end pc

I'll list out my specs in case there is a problem with my specs:
RAM: 8gb

GPU: Nvidia Geforce GTX 1050Ti

Core i7-8700H @ 2.20GHz

--------- OS SPECS --------------

x64 based processor and 64-bit operating system

Windows 10 Pro

Version 2004

OS Build 19041.450

Windows Feature Experience Pack 120.2212.31.0

--------- EDIT ------------

I even created a new big world of about 6.8 MB but it keeps changing from 6.8 MB to 11.2 MB and then it changes back to 8.2 MB

Size keeps varying everytime I enter the world

----------- EDIT 2 --------------

I tried reinstalling Minecraft and the lag spike is still there
