Game stutters on the map screen and crashes when I try to enter any location

[fraglesos]

Hello,

I've been playing for over 100 hours with no issues. Lately, during gameplay, when I was on the map sailing with my ship, frames dropped to 15-ish FPS. Also music started to sound distorted. I let the game be for a few days and things got to normal, but after a few minutes, the frames dropped again. Also, if I try to enter any location (ship battle or any other location on the map) the screen goes black, I can hear music, but no loading screen shows up. If I try to click or do anything the game crashes. I tried to wait a few minutes, but the screen stayes black. I tried the following solutions:

• Decreasing the number of logical cores as suggested here: https://steamcommunity.com/app/560130/discussions/0/2572002906843374108/
• All the steps provided here:

My computer's specs:

• Intel Core i7-9750H 2.60 GHz (6 Physical CPUs, 12 logical)
• 32 GB RAM
• NVIDIA GeForce GTX 1660 Ti

I really would like to finish the game, but now unfortunately it's impossible Please help.
