qtcreator 4.14.0-2 has been available in unstable (which you use) for more than two weeks, so reading this problem now seems slightly awkward. Have you used qtcreator 4.14.0-2 (and it code model) successfully so far in the past two weeks?
I'm usually using testing (and use unstable for double-checking before reporting bugs) and haven't really used qtcreator since Christmas as far as I can remember. (The package migrated to testing on 2020-12-28.)
My suspect is the upload of llvm-toolchain-11 done yesterday, and your package list:ii libclang1-11 1:11.0.1-2show you updated to it. Can you please try to backport your LLVM/Clang 11 packages to the same version used to build qtcreator? You can get the list of installed packages using: $ dpkg -l '*llvm*11*' | grep ^ii $ dpkg -l '*clang*11*' | grep ^ii and then use the `debsnap` tool, part of the devscripts package, to download them, e.g.: $ debsnap -d . -a amd64 libclang-11 1:11.0.1~+rc2-1 (you will need to repeat that for all the packages you have installed, removing the :amd64 suffix in the packages that have multi-arch annotations).
The issue is still reproducible after downgrading the LLVM/Clang packages this way.
It disappears when downgrading qtcreator and qtcreator-data to 4.14.0-1, though.
