Artefacts in bright bright areas

[shifuzzy]

Hi,
for some reason, my renderings are full of artefacts in the bright ares by using infinite planes or white colored floors. The denoiser can not fix that either, no matter which setting.
What am I doing wrong?
I'm working on an iMac with SketchUp Pro 2019 und V-Ray for Sketchup next (update1)
