Thanks to @ferrarirosso this will be fixed in the next release.

In the meantime you can downgrade to V2 @ferrarirosso which worked for me.

"@pnp/spfx-controls-react": "^2.9.0",

@AJIXuMuK Has this issue been fixed yet? I'm having the same issue with 3.12 version, too. Browsing to the Site or Your Organization tab and picking a library like Site Assets, results in an infinite loop of RenderListDataAsStream calls and the tenant gets throttled. Also, the issue causes the same folders to be rendered repeatedly.

@erkanch I'm no longer involved in SPFX development, but try downgrading to the package version in my above post - that worked for me at time of posting.
