You could try:
1. Open a CMD window, CD to the sqldeveloper\bin directory, run sqldeveloper.exe. See if any errors in the console.
2. Delete user settings (C:\Users\<your_userid>\AppData\Roaming\SQL Developer\system220.127.116.116.1900) and try again.
Sometimes deleting the user settings is all you need, but I have read that sometimes dual monitors are an issue. Make sure you have the latest video driver.
thank you for your answer.
I have tried this but unfortunately it doesn't show up any error. And there is no option to start SQL Developer with logging like sqldeveloper.exe -log
Also working with one screen only istn't an solution
I have tried this
Which means you tried (1) but not (2)? What happened / happens when you rename or delete the system18.104.22.1686.1900 and then restart SQL Developer?
unfortunately, i have skipped the second part.
Now it works, thank you!

I had a similar issue with an older version of SQL Developer. I tried steps 1 and 2 and they didn't work for me, but I did get it to work eventually. Here is a summary of what I did.
- Step 1: no errors appeared in the console
- Step 2: deleted the folder specified and tried to start SQL Developer again. No luck.
- I deleted the entire old SQL Developer directory and downloaded the latest version of SQL Developer. This also didn't work.
- I tried uninstalling Java per these instructions https://www.java.com/en/download/help/uninstall_java.xml then I reinstalled Java and rebooted and I was able to start SQL Developer.
On Windows 10, Java Version 8 Update 144 (build 1.8.0_144-b01)
