Thanks for the hints.
However, you should not assume that I have defined the forum as useless. A forum is always important. However, a company should always give the user a chance to communicate errors directly, and I do not mean handling errors but system-side errors, and that includes a crash.
Betas are always there to test functionalities. And no one who uses a beta assumes that it works fully. There are always restrictions and problems can occur. However, if I test an operating system, and I do this for years and give feedback accordingly, then I also test the current systems installed on each device. And if there are errors, they will be passed on to the companies for further development to incorporate these points into the improvements.
