2.1.120: TypeError "UKH is not a function" crashes `claude --resume` on startup

What's happening

On Claude Code 2.1.120 (Linux, standalone Bun-bundled binary), running claude --resume crashes immediately with:

ERROR  UKH is not a function. (In 'UKH(K)', 'UKH' is undefined)
/$bunfs/root/src/entrypoints/cli.js:9247:5663

claude (no flags) starts a fresh session normally. Only --resume (and likely --continue) triggers the crash.

Repro

1. Use 2.1.120 on Linux.
2. From any directory with prior sessions, run claude --resume.
3. Crash before the picker appears.

Tried, did NOT help

• Killing an orphaned claude --resume process from a previously SSH-disconnected session (cleaned the lock under ~/.claude/sessions/), but --resume still crashed.
• CLAUDE_CODE_DISABLE_CRON=1 claude --resume — same crash. So although the surrounding minified code shows useScheduledTasks (Av5), the actual undefined symbol UKH is somewhere else on the resume init path.

Workaround that worked

Rollback to 2.1.119 (binary still cached locally under ~/.local/share/claude/versions/2.1.119) — --resume works again.

Likely cause

Looks like a bundle hoisting / lazy-init regression on the resume code path. Surrounding code uses the pattern \$v5=(NmH(),S6(kmH)) and _v5=(NmH(),S6(kmH)) (lazy module getters). Something in that chain resolves to \undefined\ and is then invoked as a function.

Surrounding minified code (from the error frame)

var \$v5,sv4=1000,qv5=300,Kv5=5000;
var FC6=T(()=>{L\$();V\$();Tp();zb();av4();\$\$();oN();\$v5=(NmH(),S6(kmH))});
var KV4={};X\$(KV4,{useScheduledTasks:()=>Av5});
function Av5({isLoading:H,assistantMode:\$,setMessages:q}){
  let K=QD8.useRef(H);K.current=H;
  let _=B9(),A=F6(),z=Ww();
  QD8.useEffect(()=>{
    if(!TZ()||R6())return;
    ...
    let O=BC6({onFire:f,onFireTask:(M)=>{...},isLoading:()=>K.current,assistantMode:\$,getJitterConfig:t5H,isKilled:()=>!TZ(),getExtraTasks:\$V4&&Y?()=>\$V4.getRoutineCronTasks(Z_(),Y):void 0});
    return O.start(),()=>{O.stop()}
  },[\$,q,_.getState,z])
}
...
var QD8,_v5,\$V4=null;
var _V4=T(()=>{ES();L\$();h6();uT();eI();Yb();C4\$();FC6();zb();\$\$();Q3();D6();K_H();QD8=u(JH(),1),_v5=(NmH(),S6(kmH))});
