Custom Fiori App hangs on startup

Dear All,

We recently created a Custom Leave Approval App modifying the standard hcm_lrq_apv app.

The app was working properly in development, after movement to production, it is not working.

When you select the app in launchpad, the app opens up and hangs.

PFA screenshot.

Going through SCN, we found multiple solutions and have tried the following by executing these programs.

• /UI2/INVALIDATE_CLIENT_CACHES
• /UI2/INVALIDATE_GLOBAL_CACHES
• /UI2/CHIP_SYNCHRONIZE_CACHE
• /UI5/UPDATE_CACHEBUSTER
• /IWFND/CACHE_CLEANUP

Please guide.
