SP2019 Indexing Schedule Manager won't run after Security Updates KB5001944 KB5001945 KB5002018

Hi there,

We have a SP2019 On-Premises Server. After the running the following updates the Indexing Schedule Manager Timer Job won't run. Manually running Incremental and Full Crawls works fine, but the automated Timer Job fails without an error message. Any ideas?
