@Royal Tee
Thanks for your suggestion.
Unfortunately, the page you shared didn't help me, but in this case, I've just found that we can set the automation so that Dynamics gets 127 at the top of the event as a workaround for this issue.
I'll close this thread.
IIRC the dynamics are assigned to modwheel (aka MIDI CC#1). Do you have any MIDI assignment to modwheel (or MIDI CC1) inside Cubase?
Can you also check if that still happens if you untick that box:

@Jeremy_NI
Thank you for your prompt reply!
However, unfortunately, the resolution you suggested didn't work. As I mentioned, please note that this issue will happen not after I press "Play" but after Cubase (DAW) is restarted.
