Steps to reproduce:
- have clangd enabled
- have a couple of older projects inside your recent projects
- open a small project
- open another one
- close all while parsing and indexing is triggered
- back on the welcome screen, re-open the project you opened the as the last one
- while parsing close all projects
Not sure if related: these projects had not been used with clangd before. Reproducible mostly with qmake based projects. I think with qbs this did not happen so far.
See attached backtrace.
