Based on our review of the material you sent to us your lottery cut off number is Europe 45xxx.
In the July 2023 visa bulletin, the cut off number in your category is: 32,000. Per the Visa Bulletin, when an allocation cut-off number is shown, visas are available only for applicants with DV regional lottery rank numbers BELOW the specified allocation cut-off number.
Since your cut off number is above the cut off number on the visa bulletin, you are considered to be outside of the allocated numbers to be able to apply - therefore, you are not yet able to apply for your immigrant visa number via your DV Lottery Selection in July 2023.
Please note that the August 2023 visa bulletin should be published by July 15, 2023. If your number is below the published number for August, then you may be eligible to apply at that time. However, please note that USCIS will need to accept the application and process fingerprints in connection with a I-485 Adjustment of Status application. As such, there might not be enough time for USCIS to Adjudicate your I-485 case by September 30, 2023 which is the date your diversity lottery selection expires.
If your diversity visa lottery selection expires, you would not be able to file your I-485 application based on your lottery selection.
