Frequent crashes using git signing
Git commit signing is set up properly and works most of the time. Every so often though, especially after the machine has been locked for a while (after 1Password downloads an update?), when I make a git commit the "Unlock 1Password" dialog will pop up, then 1Password will crash. I then have to manually relaunch 1Password and retry the commit (which almost always works).
This has been going on for at least a year, across multiple machines. Windows is either running in a VM or is being accessed over Remote Desktop, and I believe that turning off hardware acceleration in the 1Password options has made it more stable (and fixed an issue with the unlock dialog not rendering at all...). These are work machines running the full enterprise suite of Windows Defender real-time scanning software, but 1Password itself is only connected to a personal account.
There is a crash report in the Event Log that contains this:
Faulting application name: 1Password.exe, version: 8.11.4.27, time stamp: 0x6862375f

The most recent log file in %AppData%\Local\1Password\logs ends with this:

Process: UNKNOWN_PROCESS, Details: Notify event (Modify(Any)) for paths: [C:\Users\<redacted-username>\AppData\Local\1Password\app\8\resources\app.asar]
The modified date on this file shows it was last changed a week ago. I am wondering though if Windows Defender ATP is opening the file to scan it, and that is being incorrectly detected as a modification on the file that causes the abort? Then Defender marks the file as safe, and 1Password works again until the next time an update is installed and the file changes, at which point Defender needs to scan it again? This is pure speculation, of course.
I can collect additional logging or crash dumps if instructions are provided, but the crashes seem random and I don't have a way to repro them on-demand.

The exception code 0xc0000409 is "STATUS_STACK_BUFFER_OVERFLOW".
