QtCreator regularly crashes without any sign

QtCreator regularly crashes without any sign. It usually occurs when I did something that triggers Code Completion.

There is a warning says "The use of clangd for ... was disabled, because ... memory requirements would be higher than what your system can handle." I didn't enable that later, and The memory usage (totally) is far from too full (only around 50%) when the crash occurs.

I'm not exactly sure if this still happens for newer versions, because this is already the "latest version" on apt server. I wonder if you can update it if it's handled by you?

I did not find any log about that in "~" (Searching by `'.*qt.*
.log'`).

After all, please update the version in the repository if possible.
