                      PW interact with a solid target in the presence ofa
                      relativistically underdense preplasma produced by amplified
                      spontaneous emission (ASE). Laser hole boringand
                      relativistic transparency are strongly restrained due to the
                      generation of electron-positron pairs and γ -rayphotons via
                      quantum electrodynamics (QED) processes. A pair plasma with
                      a density above the initial preplasmadensity is formed,
                      counteracting the electron-free channel produced by hole
                      boring. This pair-dominated plasmacan block laser transport
                      and trigger an avalanchelike QED cascade, efficiently
                      transferring the laser energyto the photons. This renders a
                      1-μm scale-length, underdense preplasma completely opaque
                      to laser pulses atthis power level. The QED-induced opacity
                      therefore sets much higher contrast requirements for such a
                      pulsein solid-target experiments than expected by classical
                      plasma physics. Our simulations show, for example,
                      thatproton acceleration from the rear of a solid with a
                      preplasma would be strongly impaired.},
