minecraft CRASH!? [bedrock] PC i dont know what to do. has happened all day but was fine yesterday.

Im playing minecraft bedrock on my pc. i play fine for a while and then my screen goes black for a second before turning to the mimecraft loading screen and slowly loads. all while im still in the game just sitting there. my girlfriend and i play with mods and im not sure if it has something to do with my internet, ive tried 3 ways, my mobile data. my mobile data with a vpn on and using home internet (we still live with our parents so.) im at a loss, i want to play with her but i dont want to play on my phone, i suck on it and i prefer using keys and not clicking.

ps i have also used my advanced systemcare, which deletes unnecessary things. my ideapad is completely up to date and when i try to exit out of the world so i dont die, my mouse refuses to let me ESC, or close from the tabs.. so im forced to either reset it or wait for my minecraft to load before moving/gathering my materials. it only works for a few minutes before doing this and loads for 5 and then i can move again but its so annoying. when i just want to play

does anyone know why or how to fix this.
