It's hard to know what's going on

There's a few things you can try

Try resetting your preferences:
The easiest way to reset everything is to delete the InDesign preferences: as soon as InDesign starts to boot hold down Shift, Alt, Ctrl (and Apple/Cmd if working on a Macintosh). A dialog will appear asking to delete the InDesign Preferences, select 'Yes' on this dialog.

Reinstalling rarely fixes everything - you can do a complete reinstall using the
Creative Cloud Cleaner Tool https://helpx.adobe.com/creative-cloud/kb/cc-cleaner-tool-installation-problems.html

Rollback to a previous InDeisgn version

I believe I've seen another post about error 205 thaat said signing out of Creative Cloud and signing in again was the answer.

Worth trying that...

having a similar problem. updated to 17.3 today and was unable to open InDesign anymore, when I had literally just opened it right before the update. the initializing popup would appear for a few seconds and then disappear, and then nothing would happen. i tried logging out and logging back in, which also didn't work. I'm also unable to install an older version because whenever I try, it tells me to close InDesign, which is not open. I have reset my preferences using both the shortcut and manually deleting them. I'm using Windows 11 also.

" it tells me to close InDesign, which is not open"

In that case restart your machine before doing anything.

Or lookup and kill the process in the Task Manager.
