Visual Studio si blocca all'apertura del progetto

Question

il mio progetto ha interrotto il caricamento - Visual Studio 2013 si blocca e sono davvero preoccupato di non poter continuare il mio lavoro sulla soluzione del progetto. Ho trovato questo errore nel registro delle attività di Visual Studio, ma non so davvero cosa significhi, qualcuno può aiutarti?

Visual Studio fa aperto da solo, ma non posso eseguire la soluzione di progetto su cui ho lavorato.
