Hey @maahmudur,
Welcome to the community!
That is a weird issue you are running into. What steps have you taken so far with troubleshooting?
- Have you tried updating to v5.3.1 and it still occurs?
- Try downloading the zip archive version of knime and running that. Does it also take a couple minutes to start up the editor panel?
If you download a new version and it still happens, I suspect it may have to do with memory. I would try allocating more memory in that case.
Here is a thread on it:
Also, If you are able to attach the log file, maybe there are some errors that will show up.
Let me know if any of these work,
