SQLDeveloper 23.1.1 fails on startup

Getting a long trace of errors like the following on launching SQLDeveloper?

...
oracle.ide.indexing -     org.netbeans.InvalidException: Netigso:    
C:\sqldeveloper\ide\extensions\oracle.ide.indexing.jar: Not found     bundle:oracle.ide.indexing
oracle.external.woodstox -     org.netbeans.InvalidException: Netigso:

oracle.javatools_jdk - org.netbeans.InvalidException: Netigso: 
C:\sqldeveloper\jdev\lib\jdkver.jar: Not found bundle:oracle.javatools_jdk
... 
(truncated for clarity)

On Windows, if the problem affects version 23.1.1, the solution is to delete the following hidden directory:

C:\Users\<username>\AppData\Roaming\sqldeveloper\23.1.1

Then restart SQLDeveloper.

Usually you need to enable a specific option in Windows File Explorer to visualize hidden directories and files or you enter manually AppData in the address bar when you are inside the directory with your username.

My best guess is that the same workaround applies for earlier or later versions, but I can't verify my assumption. 

Hope it helps
