I decided to write another post here rather than edit the first one, because this is important. What happened to me yesterday (see above post) turned out to be a problem with the latest Win11 beta build, 22593, being flaky. So, I don't think what I described happening actually happened because of the #23 Hotfix, but because of the Win11 build I was using. So far, these builds have been stable enough not to present problems like that. I reverted to the previous build, 22581, and all is well. Everything now works properly, I'm happy to say.
