IDE hangs on startup, with no error shown in logs

When i try to open Arduino IDE 2.3.2 it hangs at the splash screen. I have tried a few things i found in this forum with no luck.

Hi @atxfz09. Please add a forum reply here to tell us which operating system you are using (e.g., "Windows")?

I ask because I would like to give you the appropriate instructions for your operating system.

I have experienced the same problem just now,and my operating system is Windows 10
(the version of my Arduino IDE is also 2.3.2)
I tried to delete the folders mentioned in this thread: IDE hangs on startup - Software / IDE 2.x - Arduino Forum
but it didn't work.
The following is my debug output after running Powershell:
