VST Scan does not work, WIN 11, only VST3 Scan

I have Cubase Pro 15 with this kind of plugin report:

Product: Cubase Pro
Version: 15.0.30
Build: 287
Build Date: Jun 1 2026

OS Version: Windows 10 10.0.0
Date/Time: Mon Aug 24 21:59:06 2026

Total Plug-ins: 1360
Effect Plug-ins: 803
Instrument Plug-ins: 557
VST3 Plug-ins: 1220
VST2 Plug-ins: 140

and i tried the VST3 Scan of Scaler 3 Version 3.3.1 - he found 1 ( and 6 on the ignore list )!!! Instrument instead of 557. What can i do? I tried to delete the log and the plugin cache of scaler and tried the scan before and after restart of the computer. The same results scanning in the plugin and in the standalone version . It seems there are some problems with roland plugins if the roland cloud does not answer fast enough.

I switched back to Version 3.3.0. And this version foundmore than 1100 Plugins and nearly all Instruments are shown in Scaler 3.
