Cgroups are not being recognized

Short summary: Even though I'm running Arch-based Manjaro on kernel 5.18.3, Ananicy-cpp doesn't seem to properly recognize cgroups.

How to reproduce: On Manjaro installation I do:

Start with verbose output: sudo ananicy-cpp -v start.

See these snippets:

[warning] cgroup2 at /sys/fs/cgroup/ananicy_test_cgroup2 doesn't have a cpu controller available, skipping

[warning] Cgroups are not available on this platform (or are not enabled)
[trace] set_cgroup_cpu_quota: Skipping because no cgroup available

Other system utilities seem to recognize cgroups, namely, I see stuff in systemd-cgls and in systemd-cgtop.

What version do you use: Ananicy-cpp: 1.0.0_rc6

Linux kernel: 5.18.3

Configuration: ananicy.conf:

## Ananicy 2.X configuration
# Ananicy run full system scan every "check_freq" seconds
# supported values 0.01..86400
# values which have sense: 1..60
check_freq=10

# Verbose msg: true/false
cgroup_load=true
type_load=true
rule_load=true

apply_nice=true
apply_ioclass=true
apply_ionice=true
apply_sched=true
apply_oom_score_adj=true
apply_cgroup=true

check_disks_schedulers=true

loglevel=trace

00-cgroups.cgroups:

# Cgroups definitions
# Currently very simple, only for group CPU intensive tasks

# cpuquota same as systemd CPUQuota,
# only difference is - meaning of N% is all CPUs, not one core.
{ "cgroup": "cpu90", "CPUQuota": 90 }
{ "cgroup": "cpu80", "CPUQuota": 80 }

Additional details: sudo ananicy-cpp -v start output:

Further, I can see some linking of stuff to cgroups:

$ cat /proc/`pidof ananicy-cpp`/cgroup

I have the rules from: https://github.com/kuche1/minq-ananicy
