Randomly missing QML components

There seems to be some issue with Qt Creator randomly loosing components.

In QtCharts there are ValueAxis and ValuesAxis types. Typing "value" suggested ValueAxis, ValuesAxis and LogValueAxis, however, after restarting the computer I can now only see ValuesAxis and LogValueAxis. Now it also shows ValueAxis as an unknown component.

plugins.qmltypes file still has entry for ValueAxis as it should.

Qt 6.5.0-beta2 was used for testing. I tested with:

import QtCharts
ChartView {
 <start typing "value" here>
}
