Is the error 0xc0000142 fixed?

After installing Adobe Acrobat (Reader) DC version 21.005.20091, some administrators noticed that the program crashes on Windows on exit with error 0xc0000142. I had discussed the case in more detail in the blog post Adobe Reader DC 21.007.20091 crashes with error 0xc0000142, without being able to give a solution. However, it crystallized that the error might be related to a Windows security update from July 2021. The installer attempted to repair the Adobe program, which caused a crash.

The above paraphrase 4341424: Acrobat/Reader launches repair window when launched from a shortcut icon or when opening FDF/XDP/XFDF files already led me to believe that the problem might be fixed. Based on yesterday's additions to the blog post Adobe Reader DC 21.007.20091 crashes with error 0xc0000142, I did some more research. On the Adobe forum, I came across this moderator post:
