This might have been caused by my system running so slow due to the other bug I'm having with tracker-miner consuming all CPU: https://bugs.launchpad.net/ubuntu/+source/tracker-miners/+bug/1961540

The system was so sluggish that the Software Center simply did not load.

After turning of search indexing: Settings > Search, the Software Center is loading just fine.

My system had some CPU throttling issues causing Ubuntu to lag, everything is fast again now. I have set this to invalid for now.
