Looking @ bundles.info, you don’t have log4j fixes installed. It is still pointing to 2.11.2

Important! wMFix.OSGI.Platform_10.5.0.0019-0701 (OGI_10.5_Fix19) is required for upgrading Integration Server to Log4j 2.17.1. Software AG Update Manager (SUM) does not select this automatically. In SUM, you must select Infrastructure > Shared Platform > Platform 10.5.0 Fix 0019 manually. Integration Server may not start after applying Integration Server Core 10.5 Fix13 if all required fixes are not applied as well. Software AG is working to resolve the limitation in SUM.
