The previous did not work for me.
Perhaps because of the mistake that a test buffer makes assumptions about the contents that can go wrong.
Better have a separate state variable (here: buffer_on)
Code:
awk '
  buffer_on {
    buffer=buffer ORS $0
  }
  ! buffer_on && /Start/ {
    buffer_on=1
    buffer=$0
  }
  buffer_on && /End/ {
    if (buffer~/12345/) print buffer
    buffer_on=0
  }
' file

Introducing a separator variable:
one can include/exclude the Start and/or End pattern by simply changing the order of the 3 code blocks.
Code:
awk '
  buffer_on {
    buffer=buffer ors $0
    ors=ORS
  }
  ! buffer_on && /Start/ {
    buffer_on=1
    buffer=ors=""
  }
  buffer_on && /End/ {
    if (buffer~/12345/) print buffer
    buffer_on=0
  }
' file

Code:
awk '
  ! buffer_on && /Start/ {
    buffer_on=1
    buffer=ors=""
  }
  buffer_on {
    buffer=buffer ors $0
    ors=ORS
  }
  buffer_on && /End/ {
    if (buffer~/12345/) print buffer
    buffer_on=0
  }
' file

Code:
awk '
  ! buffer_on && /Start/ {
    buffer_on=1
    buffer=ors=""
  }
   buffer_on && /End/ {
    if (buffer~/12345/) print buffer
    buffer_on=0
  }
  buffer_on {
    buffer=buffer ors $0
    ors=ORS
  }
' file

Code:
awk '
   buffer_on && /End/ {
    if (buffer~/12345/) print buffer
    buffer_on=0
  }
  buffer_on {
    buffer=buffer ors $0
    ors=ORS
  }
  ! buffer_on && /Start/ {
    buffer_on=1
    buffer=ors=""
  }
' file
