I believe you're talking about the bug with the Win-X menu. Since that bug was fixed in this past week's client build, I would expect it will be fixed in the next server build. As you might already be aware, if you use vivetool and issue "vivetool addconfig 26008830 2" (for details, search and you'll find instructions/guides on that), it will workaround the issue. I did it the day 25066 came out and it's been fine since.
As a side note, this bug does illustrate how up-to-date Server is with Client nowadays. I remember when they used to be months (and sometimes years) different.
In this case, open start and search for feedback and open the Feedback Hub app and report this issue. Try uninstall your mouse driver and restart your PC to use the Windows default one and then download and install the latest driver.
Wow, yes forgot about vivetool as we used on Win 11.. didn't occur to me to try it as I assumed after they corrected Win 11 that "fixed part" would have already been integrated into this Windows 11 Server Preview haha.. anyway, that correct the issue...thanks for the reminder!
