My FPS dropped unexpectedly

[elcubo]

I have a decent laptop for the requirements of this game:

Nombre del dispositivo	LAPTOP-1VR5691E
Procesador	Intel(R) Core(TM) i5-1035G1 CPU @ 1.00GHz   1.19 GHz
RAM instalada	8.00 GB (7.78 GB utilizable)
Id. del dispositivo	98C12663-C355-47B8-AB04-D7562A6EC7AE
Id. del producto	00331-10000-00001-AA833
Tipo de sistema	Sistema operativo de 64 bits, procesador x64
Lápiz y entrada táctil	La entrada táctil o manuscrita no está disponible para esta pantalla

I have been playing normally 50-60fps for a long time, unfortunately yesterday I entered the game normally and it is unplayable 5-10fps.I tried to lower the graphics to the minimum, however not much happened. So I'd like to know what I can do to fix this,is it a bug of the game?? or my system??
