Crashing in 5 to 15 minutes every game on multiple gamemodes

My game has been crashing every 5 to 15 minutes after joining a match. I have many games of breakthrough and conquest and both result in crashes. The game's performance seems fine, but the game will randomly stutter, and then everything freezes, but I can still look around for about a second before the game closes. There is no error message, but a crash dump is generated. I have tried many methods previously suggested on the forum and elsewhere, but nothing has worked. 

The crashing started on the 1st of January

specs:

AMD Ryzen 9 7940HS, 16GB RAM, 4091MB Nvidia RTX 4070 Laptop GPU

Before it started crashing, the game ran fine with no crashes for multiple hours. I will also attach some crash dumps.

Has anyone got a fix?

Any ideas would be appreciated
