VT switching is broken in Sway, see https://github.com/swaywm/sway/issues/3612
Other than direct session Sway can use ConsoleKit2 if wlroots is built with
CONSOLEKIT port option enabled. But I don't remember if it helps VT swich issue.

Or did you mean X11? If so try xf86-video-intel + bug 236003 patch + SNA enabled.
Maybe Intel didn't push workarounds for old iGPUs from DDX into kernel.

i965 unlike iris doesn't use LLVM, so recent LLVM_DEFAULT update should
have no impact on Intel iGPUs. Unless CC/CXX is set by user llvm90 is
mainly used for libraries, not compiler.

No clue. Investigating *why* something went wrong is harder than fixing.
One way is to make snapshots of the working and non-working state then
bisect between those.
