Description of problem:
Observe https://bugzilla.redhat.com/show_bug.cgi?id=2521586#c0.
SELinux is preventing crun from 'mounton' accesses on the directory /var/lib/boinc/.local/share/containers/storage/overlay/7d838935d4ed5d8b86be2d906b8f0d458a01b6668d1d4becf245557a80bf7792/merged/sys/fs/cgroup.

*****  Plugin restorecon (99.5 confidence) suggests   ************************

If you want to fix the label. 
/var/lib/boinc/.local/share/containers/storage/overlay/7d838935d4ed5d8b86be2d906b8f0d458a01b6668d1d4becf245557a80bf7792/merged/sys/fs/cgroup default label should be boinc_var_lib_t.
Then you can run restorecon. The access attempt may have been stopped due to insufficient permissions to access a parent directory in which case try to change the following command accordingly.
Do
# /sbin/restorecon -v /var/lib/boinc/.local/share/containers/storage/overlay/7d838935d4ed5d8b86be2d906b8f0d458a01b6668d1d4becf245557a80bf7792/merged/sys/fs/cgroup

*****  Plugin catchall (1.49 confidence) suggests   **************************

If you believe that crun should be allowed mounton access on the cgroup directory by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'crun' --raw | audit2allow -M my-crun
# semodule -X 300 -i my-crun.pp
