Error getting while loading bitsream PYNQ 3.0.1

I am working on ZCU104 and trying validate PYNQ.But when am loading bitstream through jupyter notebook am getting error “KeyError: ‘PS_SUBSYSTEM_zynq_ultra_ps_e_0’”

PYNQ 3.0.1
VIVADO 2022.2
Petalinux 2022.2
Host PC : Ubuntu 20.04

I am facing somewhat similar error. When I try to load bitstream using Overlay, the Pynq is not able to load hierarchy properly. The same design I was able to work without any issue in Pynq 2.7 (Vivado 2020.2). Now once I moved to Pynq 3.0.1 and Vivado 2022.2, I am facing this issue. Attaching relevant snapshot and log

pynq-error.txt (6.4 KB)
I am using :
Vivado : 2022.2
Pynq: 3.0.1
Board: ZCU111 (RfSoC)

I just moved to PYNQ 2.7 and Vivado 2020.1 and Petalinux 2020.1
Am gettng error like this

I could resolve my error by trying this:
python3 -m pip uninstall pynqmetadata
python3 -m pip cache purge
python3 -m pip install git+

I followed this post :

CacheMetadataError - Support - PYNQ

Now I am able to sucessfully load the overlay in Pynq with Pynq version 3.0.1 and Vivado version 2022.2.
