Has space weather ever affected spacecraft launches, and do launch providers check it before spacecraft go to space?

I know there is space turbulence and it can influence a spacecraft underway, but can space weather affect the launch schedule itself?

    $\begingroup$ Not only launches, but also early termination of flight in the event of powerful flares on the Sun. $\endgroup$

    $\begingroup$ @uhoh This is not an answer, but a recitation of memories: " In the 70-80s ...There was even a case when a spacecraft was immediately de-orbited due to the data received [about the activity of the Sun]." Most likely, the text refers to a photographic reconnaissance satellite. I could not find such information about manned spacecraft. ussuriysk.bezformata.com/listnews/kosmos-sluzhba-solntca-stoit/… $\endgroup$

In 2014 a solar flare delayed the launch of a private cargo delivery to the International Space Station by 24 hours due to concerns over space radiation.

The event occurred as the commercial spaceflight company Orbital Sciences Corp. was preparing to launch a landmark cargo delivery flight to the space station with its Antares rocket and robotic Cygnus spacecraft.

The huge solar flare was rated as "an X1.2-class sun storm — the strongest class of solar flares the sun experience".
