Here, by the way, I've been wondering about this for a while. Does Red have the right to take a restart (111) when they have already passed their turn, but Blue hasn't finished their first turn?
...for now, you can take a restart even during the opponent's turn:
"each player has the right to take a restart/restarts, that is, to start a new game with a map regeneration. You can take either 3 restarts on the first day (111+111+111), or 2 restarts on the first and second days (111+112 or 112+111), or one restart on the third day (113)."
As you can see, it is not specifically stated on whose turn this can be done, but only the date is indicated, so legally, Red has the right to take a restart even during the opponent's turn. In short, a small clarification is needed, such as: "each player has the right to take a restart/restarts during their turn, that is..."
So, Neverminder
Common sense suggests that no:
during Blue's turn, many situations may arise, such as: turn duration; open scouting, during which a lot of heroes suddenly appear for the opponent, or a sufficiently strong defense is broken, and much more, I just can't remember it right now...
I've made a correction:
Subjective Restarts:
each player has the right to take a restart/restarts during their turn, that is, to start a new game with a map regeneration...
Restart after the first encounter...
If the encounter occurs within the specified time, either opponent has the right to demand a restart immediately after it...
