For instance, repro step is:
  1. Run VRChat.exe in desktop mode
  2. Press
    Shift
    key and continue to pressing
  3. Type
    Alt + Tab
    and change active window to some other app
  4. Stop pressing
    Shift
    key
  5. Type
    Alt + Tab
    and activate VRChat window again
  6. Type
    ESC
    key, then the safe mode is activated. Though the safe mode is bound to
    Shift + ESC
    and you don't press
    Shift
    key.
All key inputs seems behave as same. for example if you try
W
then the avatar continues to walk forward.
