3:02 PM PT -- Ryan Garcia's attorney, Michael A. Goldstein, tells TMZ Sports ... he and his client are hoping to reach a quick resolution in the case -- as the star boxer has already reimbursed the Waldorf Astoria for the damage he caused.

In addition, Goldstein says Garcia has expressed sincere remorse for his actions ... and has also apologized to employees at the luxury hotel as well.

"The past several months have been difficult for Ryan and he understands he has reached a crossroads in both his personal life and career," Goldstein said. "Going forward, he knows the focus must be on his well-being and mental health issues which have been strained."

"There is no alternative. He apologizes to anyone he has offended with his behavior and words and hopes the investment in his own well-being will demonstrate the sincerity of his apology."

Ryan Garcia was just hit with a misdemeanor vandalism charge stemming from his alleged meltdown at a swanky hotel in Los Angeles ... and now, prosecutors say he could be facing up to one year behind bars over it all.

The star boxer was first accused of the crime back on June 8 ... after authorities claimed he snapped and wrecked a room and a hallway at the Waldorf Astoria Beverly Hills.

In video we obtained from the scene, you can see multiple officers led the 25-year-old pugilist away from the hotel's premises in handcuffs.

L.A. County District Attorney George Gascón announced Thursday Garcia was formally hit with one count of vandalism $400 or more in damage or destruction of property, which carries a maximum sentence of 12 months behind bars if convicted.

He is now expected to appear before a judge on Aug. 7.

"While we are grateful no injuries were reported in this incident, reckless behavior that damages property shows a blatant and unacceptable disregard for the safety and peace of our community," Gascón said. "Our office will work to ensure the responsible individual is held accountable."

We've reached out to Garcia's attorney for comment, but so far, no word back yet.
