v3.14 fails with target framework net461 ... net48 on linux (ArgumentException: The net-4.6.1 framework is not available.), but v3.12 works well

[devizer]

Intro: We need nunit-console to test NET Standard Libraries on mono-only platforms such as armv6, Raspberry PI zero, etc. v3.12 did it well, but the latest v3.14 fails.

For v3.14 the output on a Linux for net4.6.1 test assembly is:

v3.12 works well.
How to reproduce:

NETFW=net461
work=$HOME/transient-builds/src
mkdir -p $work && cd $work
echo "git clone|pull"
test ! -d Universe.CpuUsage && git clone https://github.com/devizer/Universe.CpuUsage || true
cd Universe.CpuUsage
git reset --hard; git pull
echo "Reset target framework to [$NETFW]"
Reset-Target-Framework --framework $NETFW --language latest
echo "Restore Dependencies"
cd Universe.CpuUsage.Tests
msbuild /t:Restore -v:m
echo "Build Release for Universe.CpuUsage.Tests"
msbuild /t:Build /p:Configuration=Release -v:m
cd bin/Release/$NETFW
echo "Run Integration Tests"
nunit3-console --workers=1 Universe.CpuUsage.Tests.dll
echo "Successfully completed"

nunit3-console is a shell-link:
mono /...path...to...nuget..package/packages/NUnit.ConsoleRunner/tools/nunit3-console.exe "$@"
mono and msbuild: the latest from official Xamarin repo, 6.12.0.122
OS Ubuntu 18.04 LTS (actually Linux version doesn't matter)

Below just references how to simplify reproduction step
Reset-Target-Framework scripts above resets Targetframwork[s] to specific version for csproj-files. here is it: https://github.com/devizer/test-and-build/blob/master/lab/permanent-scripts/Reset-Target-Framework.sh

v3.12 can be installed via snapshot.gz using shared script:
https://github.com/devizer/glist/blob/master/bin/net-test-runners.sh

The latest version of nunit-console can be installed via nuget using another shared script
https://github.com/devizer/test-and-build/blob/master/lab/NET-TEST-RUNNERS-build.sh
As of now, it installs v3.14

Azure DevOps pipeline failing after updating NUnit.ConsoleRunner nuget package to to 3.15 version. Command use to run the nunit test:
