Please help ! Platform locked after customization of "origin product version"

I added a code to display a default value: ###EVAL### $value='Select Version' AND ###EVAL### $value='Select Component'

For the "Origin product version" & "Component" drop down list.

Since I saved, the platform is unresponsive, I automatically get logged out. I cannot change as I'm always disconnected.

Same when I connect as user, always being disconnected.

DEV and PRODUCTION issue ! Please help ASAP

Any user trying to create a ticket is being logged out automatically

I attached log

There is an SQL exception logging the user out. The exception seems to be only on the ticket creation screen / preview of screen customization (right side)

A workaround could be to deactivate the preview window in the customization screen module. This preview window logs me out when I select "Ticket"
