Adding a fuel tank make it impossible to select a part and to save or quit the rocket editor

[sylario]

build id = 03045

- Game reinstalled and file checked
- No mod installed.

In career mode, after the very first flight with 3 mystery goo, I have enough science to unlock the 2 first elements of the research tree.
In the rocket editror, I put a control pod and a decoupler. When I try to add the (only) fuel tank, it fails. The fuel tank diseapear, and now I cannot select an existing part. I also cannot exit the VAB. The logs are the following :

The same parts in sandbox mode have no problem at all.

Reminds me of this issue, maybe related? https://bugs.kerbalspaceprogram.com/issues/27045

No, the only thing dissepearing in my case is the part to be added, not the whole ship. Also I am also stuck in the VAB with the exit button with and without save that are unresponsive.

If you can reproduce it, it would be a good idea to report that issue in the official bug tracker, that is what the developers do read.

Have you tried completely uninstalling the whole game (i.e) the files that actually contain the fuel tanks, and reinstalling the latest version. What seemed to have happened is that I had the old textures of 1.7 fuel tanks, which confused the game, made it bug out and disappear probably thinking that it should not be possible to place things that don't exist etc.
