Since the new patch my game is sometimes crashing with the identical error message.
Exception: 0xC0000374 (HEAP_CORRUPTION) at 00007fff7b07dc45 0x00007fff7b12e0e0
I tried to apply multiple fix attempts from other sources, but without any luck. I truly believe someone messed up with memory management.
The exception summary is also always the same:
<Exception.Summary:>
0xC0000374 (HEAP_CORRUPTION) at 00007fff7b07dc45 0x00007fff7b12e0e0
(DBG-OPTIONS<FunctionsOnly SingleLine> DBG-ADDR<00007fff7b07dc45>("ntdll.dll") <- DBG-ADDR<00007fff7af977f9>("ntdll.dll") <- DBG-ADDR<00007fff7af78c02>("ntdll.dll") DBG-OPTIONS<>)
<:Exception.Summary>
What I tried so far:
- Removing custom spell icons
- Going from DX12 to DX11
- Running game repair
- Resetting interface
- Reinstalling the game
- Installing latest drivers
- BIOS flash for Intel issue (did this long time ago)
Also other users experience the same:

Solution
I am almost very sure that this is a driver problem from the latest NVIDIA drivers. After feeding Claude AI with the log files and trying some of the proposed fixes, it narrowed it down to driver issues. In the Reddit thread someone from NVIDIA also requested dmp files for further analysis. I installed a rather old driver version yesterday v561.09 and so far I had no heap corruption crashes. My mate never experienced a crash like this and he was playing on v560. Claude was telling me that anything beyond 566.x might be affected, but take it with a grain of salt.
