I have found where the problem is. In “all-bootstrap-blocks/src/scss/bootstrap-5.0.2/_offcanvas.scss” the offcanvas-backdrop class has wrong values.

.offcanvas-backdrop {
  position: fixed;
  top: 0;
  left: 0;
  z-index: $zindex-modal-backdrop;
  width: 100vw;
  height: 100vh;
  background-color: $modal-backdrop-bg;

  // Fade for backdrop
  &.fade { opacity: 0; }
  &.show { opacity: $modal-backdrop-opacity; }
}

here it should be offcanvas-backdrop. But it is currently somehow modal.
The offcanvas works fine with other bootstrap versions.
It would be helpful if it s fixed, as the version 5.0.2 is the default.
