Hi Manish,
I just tried the following flags (V8 v13.8.258.19) on Windows.
dcheck_always_on = false
is_component_build = false
is_debug = false
symbol_level = 0
target_cpu = "x64"
use_custom_libcxx = false
v8_enable_i18n_support = false
v8_enable_pointer_compression = false
v8_enable_sandbox = false
v8_enable_temporal_support = true
v8_monolithic = true
v8_monolithic_for_shared_library = true
v8_static_library = true
v8_target_cpu = "x64"
v8_use_external_startup_data = false
It still doesn't work. Here are the errors.
MSBuild version 17.13.19+0d9f5a35a for .NET Framework

I'm not sure what went wrong.
