TortoiseSVN Checkout dialog is delaying a lot to popup

[dring xu]

Hello,

Issue backgroud:

1. brandnew PC with Win11.

2. latest TortoiseSVN (TortoiseSVN-1.14.9.29743-x64-svn-1.14.5.msi) was installed.

Issue details:

ContextMenu -> TortoiseSVN->Repo-browser menu works.

I can view all files

But if I use "Checkout"  Contextmenu, "Checkout Dialog" is delaying a lot, then popup.

I tried to uninstall/install many times, and also tried some other TortoiseSVN version, all are the same behavior.

May you please help check what may be the root cause?

Thank you very much.
