times loop functionality does not support break, throws Null Pointer Exception

Description

When attempting to break from a loop using the newer `times` functionality (https://docs.lucee.org/guides/lucee-5/times.html) you get a Null Pointer Exception. This occurs in both cfscript and tag.

Only tested on the 2 latest versions my apps are running.

<cfscript> loop times=10 { break; } </cfscript> <cfloop times=10> <cfbreak> </cfloop>

Environment

commandbox:alpine docker latest

even simpler repo

<cfscript>     q_users = QueryNew("user");     loop query="q_users" {     } </cfscript>

can’t repo as a test case tho, but it happens for me with tomcat on 5.3.4.2 and 6.0.0.529

Just got caught by this… Lucee 5.3.6.61; nothing else to add.

I've checked this ticket and confirmed the issue happened on lucee latest version 5.3.8.3-SNAPSHOT also. Using break in loop times functionality throws a NullPointerException.
