Root cause is API change in WorldPainter: Captain-Chaos/WorldPainter@cdedbe9#diff-2c4ceef0263041cef7c66126b5f645c65bca23aa64951112d8dc54816f756595

I managed to fix the error, do this step by step:
Step 1: Uninstall the current version of Worldpainter.
Step 2: Install Worldpainter 2.7.18 from this link.
Step 3: Install Java 8 from this link.
Step 4: Press Win + R, type regedit, and hit Enter.

Step 5: In the Registry Editor, navigate to HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\JDK"your java version ( for me it is 17.0.11)"




Step 6: Double click the JavaHome file inside your java version folder (which is in the JDK folder)
Step 7: Change the JavaHome value to the path of your java 8, for me it is C:\Program Files\Java\jre1.8.0_431.

I managed to fix this issue thanks to the Reddit post, all credit goes to him!

If you'd like to revert the change, please follow the steps but change java 8.
