[10] In 2024, after the championship's collapse, former W Series driver Abbie Eaton claimed that some of Flörsch's arguments were "completely deluded" and that "a lot of the time it's her dad posting on her social media".

[25] She was later diagnosed with a spinal fracture, for which she underwent a surgery lasting almost 10 hours the following day, subsequently reported as successful with "no fear of paralysis", by her race team leader, Frits van Amersfoort.

[30] In early November, it was confirmed that Flörsch was placed on the team to compete in the 2019 Macau Grand Prix, with support from several Macanese companies and notable people.

[31] She failed to finish the race after her car suffered a mechanical failure which left her stranded ahead of the Mandarin Oriental Bend on the eighth lap.

[3] Having focused on collecting data in the first few rounds,[35] Flörsch achieved her and PHM's first points with 9th place at the Red Bull Ring, only to then lose the result to a post-race disqualification.

[42] Flörsch remained with Van Amersfoort Racing for the 2024 season,[43] but failed to build on her previous year, recording a best finish of 11th as teammate Noel León made the podium four times.

[47] She continued with Richard Mille in 2021, this time in the FIA World Endurance Championship, where she led the team to five points finishes and qualified a season-best 6th at the 8 Hours of Bahrain, ahead of Formula One race winner Juan Pablo Montoya.

[48][49] She also received a call-up from Algarve Pro Racing to replace Diego Menchaca in the 2021 European Le Mans Series season finale at Portimão.

[51][52] Flörsch later appeared in the post-season FIA World Endurance Championship rookie test in Bahrain, driving for newly-crowned LMP2 champions Team WRT, where she led both sessions.

[53][54] In 2022, Flörsch left the Richard Mille project to join G-Drive Racing and make a full-time return to the European Le Mans Series, driving one of the team's two Oreca 07 LMP2 cars alongside Roman Rusinov.

Algarve Pro Racing, who were set to run G-Drive's cars, took over independently, signing Flörsch and F2 podium finisher Bent Viscaal.

[56][57] That was to be the high point of their season though, as a late puncture at Imola, an untimely full-course yellow at Monza and a pit-lane start at Barcelona limited their next results, before Flörsch vacated her seat for the final two rounds.

[60][61] Alongside her FIA WEC programme, Flörsch raced in the 2021 Deutsche Tourenwagen Masters for German team Abt Sportsline with backing from Schaeffler.

[63] In December 2024, Flörsch signed with HMD Motorsports to compete in the 2025 Indy NXT series, shifting her career to United States-based racing.
