WaitFor Method not working

for a few days now my script throws me the following error:

Unable to wait for object ‘Object Repository/[folder]/[object]’ to be visible (Root cause: java.lang.NoSuchMethodError: org.openqa.selenium.support.ui.FluentWait.until(Ljava/util/function/Function;)Ljava/lang/Object;)

The error occurs for no matter what element I want to wait for.
It worked absultely fine before, and I dont think i changed something. Also tried another website to test on.

I thought it was just me. I am seeing the same issue, Katalon v5.2.0 Build 1.

Fixed (for me, at least) - I deleted the entire Katalon folder and copied from the zip file again. Must have been some leftover files from a previous ‘installation’.

worked for me, too. Thank you.
