Fortnite causes BSOD on HP Pavilion notebook

[Arginnon]

Hi! I first went to Epic Games with this problem, they sent me to Microsoft, who've told me to contact the device manufacturer, so I hope someone here will be able to help me.

I've been playing Fortnite on my HP Pavilion 15-n002sh notebook, running Windows 8.1, with Intel Core i5-4200U CPU, 8 GB RAM and AMD Radeon HD 8670M GPU. Everything worked fine for months, then after the previous update (v21.20) the game started causing an IRQL_Not_Less_Or_Equal stop code (Blue Screen of Death) whenever I join a game. Nothing else was changed on the PC, only Fortnite was updated, and it's only Fortnite that causes the crash.

Since then I tried fixing it by:

• launching the game in different rendering modes (I play in performance mode but the problem persists in the other two as well)
• verifying the game files
• completely uninstalling the game and launcher then reinstalling it
• running it as an administrator
• adjusting the compatibility settings
• reinstalling Battle Eye and Easy Anti-Cheat
• updating the graphics card drivers
• checking for windows updates
• disabling the antivirus software (Avast)
• checking for viruses
• repairing visual C++ redistributables
• running diagnostics and stress tests on the memory and the graphics card (they're both working fine)
• performing a clean boot

None of the above worked. Since then I found some other players on reddit who're saying that they encountered the same issue after the update, similarly on Windows 8.1.

I also generated a complete memory dump and this is what the analyzer said:

On Sun 2022.07.17. 14:50:01 your computer crashed or a problem was reported

Crash dump file:	C:\WINDOWS\MEMORY.DMP (Full memory dump)
Bugcheck code:	0xA(0x10, 0x2, 0x1, 0xFFFFF801F5A74509)
Bugcheck name:	IRQL_NOT_LESS_OR_EQUAL
Driver or module in which error occurred:	Program.sys  (FortniteClient_Win64_Shipping_7ffb056f0000!Ordinal0+0x2936230 )
File path:	C:\Program
Bug check description:	This indicates that Microsoft Windows or a kernel-mode driver accessed paged memory at DISPATCH_LEVEL or above. This is a software bug.
Analysis:	This is a typical software problem. Most likely this is caused by a bug in a driver.
Google query:	FortniteClient_Win64_Shipping_7ffb056f0000 IRQL_NOT_LESS_OR_EQUAL

I'm a bit of a noob, so I have no idea how to make sense of this or how to proceed. Any help is appreciated!  Thank you so much in advance!
