couldn't start dropbox

[ArqSanabria21]

Buenas tardes, todo comenzó en julio 2020 un mes de mi suscripcion anual. una compañera debido a cuestiones de ella  no me mando una solucitud de prueba de dropbox business, depues de ello me salio el siguiente error. llevo varios meses peliandome. descubrí que si desistalaba e instalaba después de cada reinicio, podia trabajar en vez de peliarme con el fastidioso sistema de ayuda...
13 de abril de 2021 ahora ya no puedo ni instalarlo y no me dan solucion. recurro a ustedes en ayuda!. anexo imagen.
