I suppose you are refering to the former Windows 10 Edition. In that case, try hard-closing Minecraft from the Task Manager (Ctrl+Alt+Supr and then click on Task Manager) if it is open, and then try re-opening the game. If your problem persists, try reinstalling Minecraft from the Microsoft Store.
Just play without the resource pack or with a lower resolution one, as the highest the resolution, the lower the game's performance. If you could upload a video showing how the resource pack affects the game performance, it would help a lot.
