@IEPforAUR As monarc99 already commented, the Chromium development versions (which ungoogled-Chromium is based on) are originally developed with clang 13 (trunk versions) in mind.
So in Manjaro, you have two options:
1) Set the source to compile using the toolchain supplied by the Chromium developers, which includes clang 13 trunk.
To achieve this, you will have to make the following modifications to PKGBUILD (taken from the chromium-dev AUR package):
_clang_path="${BUILDDIR}${_builddir}/src/chromium-${pkgver}/third_party/llvm-build/Release+Asserts/bin/"
export CC="${_clang_path}clang"
export CXX="${_clang_path}clang++"
export AR="${_clang_path}llvm-ar"
export NM=nm
export RANLIB=/usr/bin/true
_lld="ld.lld"
msg2 "Download prebuilt clang from Google"
tools/clang/scripts/update.py
2) You can try to compile the sources with clang 12 but they must be patched:

A new va-api patch for wayland has been added. Required flags for it to work are the following, thanks to @acidunit

Please do NOT flag this package as out of date in relation to official chromium releases.
This is NOT Google Chromium and new releases come after additional work of the ungoogled-chromium contributors, so they may not be ready, nor available for days or even weeks after a new version of official chromium is released.
Please refer to https://github.com/Eloston/ungoogled-chromium/tags for ungoogled-chromium releases. Use those and please flag this package as out of date only if a newer release is present there. I will update the PKGBUILD as soon as I can every time a new release comes out.
Thanks
