Zwift hängt sich nach dem Starten sofort auf

Sehr geehrtes Zwift-Team,
Als ich vor knapp zwei Wochen 15 Minuten in meiner Fahrt war, ist Zwift auf meinem Desktop-Pc plötzlich abgestürzt. Als ich es erneut starten wollte, hing sich das Programm erneut auf sobald ich in der Wahl für das Powermeter, Hf-Gurt, etc. bin. Auch eine Reinstallation sogar mit dem Entfernen aller Daten und eine Aktualisierung meines Geforce Treibers haben nichts gebracht. Genauso wenig Deaktivieren der Firewall, etc. Leider hängt das Programm sich nach dem Start immer wieder im Menü auf. Was kann ich dagegen tun? Ich habe alles versucht und bin echt ratlos! Ziemlich scheiße, weil Einheiten von einer Länge von mehreren Stunden echt langweilig sind nur mit dem HAndy als Zwift, zusätzlich habe ich keine Widerstandsanpassung bei der Rolle und der Erg mode geht auch nicht, Hoffentlich könnt ihr mir helfen. Hier die Log-Datei:

From the log file snippet above it looks like you enter the pairing screen, and then the program exits.

Do you use ANT+ or BLE (Bluetooth)? If the latter, try to install vc_redistx64.exe (it is probably in the %programfiles(x86)%\zwift folder or can be downloaded – see link here: Zwift PC Bluetooth issues

If that doesn’t help I recommend you contact Zwift Support with your problem.

You are such an angel!
I wrote the support twice, but they didn´t help and three hour Indoor-rides without the erg-mode are so boring!
Thank you so much! I´m so happy right now!
