Not sure what is happening her SSteel
You could try the following:-
Use JSGME to unistall all mods
Delete your MODS folder form SH5 dir (Copy from your MODS folder all the mods you want to keep first)
Run JSGME (this will make a new MODS folder)
Add TDWs UI and OHII only to MODS folder.
Run game a test without any mods installed. If ok-
Add TDWs UI - test again - if ok-
Add OHII - test again
If you still get the issues with only these two mods-
Run JSGME valitador and post report
Run SH5 validator and post report
