Adding /Isolate via Directory.Build.rsp applies it to all MSBuild executions (including local dev builds and IDE-driven builds), and may fail on environments where the MSBuild version doesn’t recognize the switch. If the intent is CI-only or limited-scope usage, consider moving this flag into the CI/build scripts instead of Directory.Build.rsp; otherwise, pin/standardize the build toolchain (e.g., via global.json and CI image/tooling updates) so all supported environments use an MSBuild version that supports /Isolate.

Suggested change
/Isolate
# /Isolate flag removed from global response file.
# If isolation is required, pass /Isolate explicitly from CI or build scripts
# instead of applying it to all MSBuild invocations via Directory.Build.rsp.
