Podman Error mkdir /home/plcnext_firmware/rundir/libpod: No such file or directory

Hello,
since firmware version 2021.9.0 Podman is integrated in PLCnext. According to the change notes, podman is currently only available for PLCnext Store apps. These are executed under the user plcnext_firmware. However, when executing simple podman commands on the command line with the user plcnext_firmware I always get the following error:
image.pngA correct execution of the commands is only possible with the user root.
Does anyone have an idea how to fix this error?

Firmware: 2023.6.0
podman-Version: 4.4.3
