Premiere 26.0.1 not support UXP Developer Tool ( No applications are connected to the service. Make sure the target application is running and connected to the service)

After installing Premiere Pro 26.0.1, I tried running my UXP plugin using UXP Developer Tool, but it fails to load.

I get the following error message:

The plugin does not run at all.

Before upgrading, it was working properly in the previous Premiere version.
Premiere 25.6.2 Version is OK

    Hi ​@gwang heih87095946 - Can you check your Preferences under Plugins and make sure the “Enable developer mode” is checked
