[severity:It bothers me. A fix would be nice] [regression] [worked-in:17.1]
When opening VS 2022 17.2 Preview 1, the first code file that gets displayed - i.e. the file that was open when I last closed it - does not get proper syntax coloring.

The workaround is to close that file and reopen it.

Other files do get proper syntax coloring when I switch tabs.
