[2022] Game keeps crashing on Windows 11

I bought the game recently, and it worked fine for the initial 3 hours of gameplay. However, the game is recently crashing frequently within the first 3 -10 minutes of gameplay.
I have performed the below steps on my PC to troubleshoot the problem:

1. Update the Windows 11 updates
2. Update the graphic card drivers
3. Re-install the game from Ubisoft connect. I downloaded the 110 GB game again.

Below are the configurations:

1. Ryzen 7 Octa Core 5800H 
2. NVIDIA GeForce RTX 3050Ti
3. 16 GB RAM

Now, I am clueless about the issue and hence reaching out for help.
