you can try load 11.4 version, then create config backup (ucs file). after that, load 11.6, load default configuration (tmsh load /sys config default) and then load previous created ucs backup file.
when problem occurs again, look into log or error message (e.g. /config/bigip.conf at line: 7396) and check what's wrong (e.g. look into config at that line). helpful can bee load config partition after partition (load /sys config partitions { PARTITION-NAME }) and not all partitions together (load /sys config partitions { all }). there is possibility load config step-by-step from terminal (copy-paste), it depends on size of configuration.
let us know if you solved your issue.
Thanks for response. Line 7396 contained spaces: send "GET /betstream/getEvents HTTP/1.1\r\nHost: \r\nConnection: Close\r\n\r\n"
Seems there is bug, which covers that issue https://support.f5.com/csp/article/K15144
It takes place only when reloading config (load /sys config) or restoring from ucs files
