Investigation

Both BlazorWebTemplate_CanUsePasskeys and BlazorWebTemplate_CanRequireConfirmedEmail fail during the shared template-publish step (CreateBuildPublishAsync → dotnet publish) with the same root cause: error RZ1021: Markup in a code block must start with a tag and all start tags must be matched with end tags. in the generated Components/Account/Pages/Manage/EnableAuthenticator.razor file, specifically flagging an unclosed <br> tag (line 19) that should be a self-closing <br/>.

This is a Razor compiler diagnostic surfacing during the Individual-auth Blazor Web template's publish step against an EnableAuthenticator.razor page that ships as part of the Identity scaffolding in the template. Since both failing tests share the same -au Individual template configuration and publish path, they are almost certainly hitting the exact same generated-file markup issue rather than two independent flakes — likely a template content regression (an unclosed <br> tag introduced in the Identity UI scaffolding) intermittently tripping the Razor source generator/compiler under certain SDK preview builds, or a race in incremental publish/restore causing stale generated markup to be re-evaluated. I could not confirm from within this sandboxed run whether the <br> in the actual template source is genuinely unclosed (which would make this a deterministic bug rather than a flake) — a maintainer should check EnableAuthenticator.razor in the Identity UI scaffolding template for an unclosed <br> tag around line 19 as the most likely fix.
