Multiple Crashes with the same cause

Path of Exile Crash Report – Invalid Pointer Write (0xC0000005)

Summary:
This report includes details from five recurring crashes in `PathOfExile.exe`, all exhibiting identical behavior:
- Exception Code: `0xC0000005` (Access Violation – Write)
- Faulting Instruction: `mov dword ptr [rbp+2CA8h],1`
- Crash Address: `PathOfExile.exe+0xEE0FD4`
- Cause: `rbp = 0x0`, leading to a null pointer dereference

Pattern Observed:
- All five crashes occurred during active gameplay within 1 to 180 minutes of launch.
- Stack traces consistently follow the same pattern, pointing to a repeatable internal code path failure.

Crash Details (Summarized):


Stack Trace Snapshot (Consistent Across Dumps):

"

PathOfExile.exe+0xEE0FD4
PathOfExile.exe+0xEE0E61
PathOfExile.exe+0xEE17D6
PathOfExile.exe+0xEF0E0A
PathOfExile.exe+0xCCA340

Diagnosis:
- The instruction at `PathOfExile.exe+0xEE0FD4` writes to `[rbp+0x2CA8]` without checking if `rbp` is null.
- All dumps show `rbp = 0x0`, causing consistent access violations. This suggests:
- Use-after-free, or
- Invalid context object passed to internal function

Requested Action:
Please investigate the function at `+0xEE0FD4` in `PathOfExile.exe`, as this site is the source of multiple repeatable crashes under normal gameplay conditions. If helpful, I can supply the actual `.dmp` files or full `!analyze -v` outputs.

Thank you for reviewing this report.

User Gameplay Context (Reported by Player):

- Crashes were historically rare, occurring only intermittently.
- Recently began using Scarab of Wisps, and crash frequency spiked significantly.
- In one map containing 2 Wisp Scarabs + natural Wildwood spawn, the game crashed 4 times.
- The same mapping strategy was used for over a week with Abyss Scarabs and showed no issues.
- This suggests a strong correlation between Wisps mechanics and the invalid memory write crash.

This is a problem in Windows or your security software preventing memory access to the app or folder where the files are located.

You can try adding an exploit protection exception to Windows Defender for poe.

I will try it, but I don't think it would make sense for it to be a security issue based on detailed crash analysis using WinDbg and symbol-agnostic reverse engineering. There are no exploit mitigations events (DEP or CFG). The timing of it all I don't think makes sense as a security issue either.

As for it being a System issue (Windows), I think the fact that the stack trace is identical across the crashes shows that it isn't just random interference. The exact same code is causing the failure every time.

e2/ further testing has shown no improvement since last patch that fixed 3 instance crashes and adding exceptions to windows defenders for poe. I crash on average once per map when using wisp scarab. When there is also a wildwood, I crash 4+ times in that map.

PLease fix. I can't play the strat I want - Alva - because I lose shrine buff every time I crash which is almost every map.
