FMX app hanging at start after Windows 11 run for a long time(a few hours).

 

Anybody here notice that when the Windows 11 runs for a while such as a few hours, And my FMX app will be hanging at startup, but I tried to start other apps, there is no such problem. I tested use delphi to create a empty form FMX app, it is still hang when startup, but VCL app will run fine.  In this case, the Delphi IDE also has many problems, such the form design window will not load the fmx form and show it, the Object explore and the properties of the form element also do not shows anything,  And the popup menu of Delphi IDE will not show the mouse highlight background, and some dialog form of Delphi IDE will not accept mouse click, but if you move keyboard to the buttons on the form, it may(or not) works.  I try to open the tools option and User interface and form designer, High DPI, the listbox do not show any listitems in it, and the checkbox show white blank, can not see any words in the text area.  And the checkbox  could not click/ select or deselect by mouse click.

 

And there seems more problem. But the mostly problem is the FMX app can not run at start up, If I try to start the FMX app repeated by shutdown it in the task manager, After a few retries such as 5 - 20 times, it may startup without any change of the OS. 

 

When the problem happens, My Memory shows about 45% (48G total) use, and CPU about 50%( I5 13400F )  usage.  

 

Other strange problem the Firefox browser can not copy any text in the web page, and  the popup menu of taskbar could not response to mouse too, but you can move up/down button of keyboard to select the popupmenu item and click it to call the command.

 

I am not very sure what's cause this, the probem effect the FMX apps and Delphi IDE,  but seems not effect VCL apps.

 

It is worse that the problem happens every day on my PC.

 

Anybody with advice or have a solution?

Thank you.
