I am not going to say it will solve the issue but be aware that a lot of improvements changes where made wrt QT after Lazarus 4.0RC. You are (still) at version 3.8.

I would suggest trying the same sequence with Lazarus 4.0RC1/RC2 or perhaps even trunk.

after several testing, with qt6 and qt5, the problem is not with qt,
but when installing anchordockingdsgn, the problem appears.

Hopefully someone can fix this problem
