edit: i verified that it's related to lsp function, after i disabled from config ("lsp": false) it was able to write to the file.

same issue， works after disabling LSP.

This is likely due to a network issue. OpenCode will attempt to download the corresponding LSP Server. In my case it's Java LSP(JDTLS), and after I provide it manually, everything works fine.

In my case, OpenCode was installed via Nix into the
/nix/store/opencode/...directory, which is strictly read-only by design.This prevents the application from writing or modifying files within that path.
