OpenCode has had issues with Windows network mapping support since a certain version

Question

I use network mapping in Windows to map a WebDAV directory as a local drive (like Y:/), and I open a directory under this drive (Y:/some_dir/) with OpenCode. However, after OpenCode opens this directory, the status bar shows something like \\localhost@40101\DavWWWRoot\ instead of the actual path Y:/some_dir/. This causes frequent errors when I write code in OpenCode (such as file not found, etc.), and even leads to OpenCode crashes.

I remember that in versions of OpenCode before a certain release (maybe v1.2.20?), the status bar displayed the actual path Y:/some_dir/, and I could write code happily without encountering some inexplicable errors.

Thanks for the report. Could you provide more detailed reproduction steps, especially for the crash?

In particular, it would help to know:

the specific actions that trigger “file not found” errors,

the exact steps that cause OpenCode to crash,

whether the crash is consistent,

and any logs, screenshots, or error messages.

A minimal reproducible example would be ideal.

The information of the environment I am using is as follows:

Operating System: Windows 11 25H2 Build 26200.8037
opencode Version: 1.2.27 (No custom instructions, plugin, or agent configured)
Model: qwen3.5-plus
Working Directory: A WebDAV storage mounted as a local disk via network mapping (Y:)

The steps I followed are as follows:

Open pwsh, switch the working directory to Y:\z\dcs-cloud-app, and launch opencode.
Then \\localhost@40101\DavWWWRoot\... is displayed in the bottom-left corner of opencode:

After waiting for a short while, opencode crashes with the following error message:

TypeError: undefined is not an object (evaluating 'sync6.data.path.directory')
    at <anonymous> (B:/~BUN/root/src/index.js:360654:38)

    at setStore (B:/~BUN/root/src/index.js:343459:10)
    at processTicksAndRejections (native:7:39)...

Due to the fact that opencode crashes shortly after being launched, I am temporarily unable to reproduce errors such as "file editing error" and "file not found". I sincerely apologize for this inconvenience!

Sorry, I haven't been able to reproduce this on my side so far.
I tested a similar setup on Windows with a WebDAV-mapped drive. I also saw the path briefly change to \localhost@40101\DavWWWRoot..., but opencode continued to run normally and did not crash.
At the moment, I can't tell what is different in your environment or which part is failing. I'm sorry that I don't have a more concrete lead yet.

I will fix this, many path things coming down the pipeline

Thank you both for your attention to this issue! I will also try reinstalling opencode or testing on another computer to see if I can gather more information about the problem.

Update:

In the latest version (1.3.13), I tried to run opencode in the WebDAV drive (Y:/project/), but got a new error like this:

Error: Unexpected error, check log file at C:\Users\1234\.local\share\opencode\log\2026-04-02T032438.log for more details

Unknown: FileSystem.access (\\localhost@40101\DavWWWRoot\.git)

And the following is the full log content (2026-04-02T032438.log):
