Megasync do not work

Megasync do not work for a fresh cachyos installation. No matter which package I try (megasync, megasync-bin, megasync-nopdfium, or official megasync from the mega webpage). Launching from terminal gives me a message: “Avoiding wayland” and nothing happens.
Installing icu74 from the AUR did not help.
People say that they have this problem on CachyOS but other distributions are not affected like Endeavour + KDE or Manjaro + KDE (link)

QT_QPA_PLATFORM=xcb is required as env variable
