I installed Knime version 5.3.4 and it worked.

But one day later When I try to open , I can not open.

I got this message. Then I finally reinstall knime and it worked.

Maybe is there any alternative solution?

Hello @hadi,

sounds like corruption. Considering you reinstalled there’s no much you can do now as log with error does not exist anymore. If it happens again check/share log.
