Hello,
Unfortunately, the update to 12.3.431 doesn't help.
For me, the problem can also be reproduced if I make an other screen to the main screen. Than the Start of SSMS will freeze. Switch main screen back to my Laptop screen and all works fine.

Do I understand correctly that you have 3 monitors? Depending on which monitor you have SSMS shown, it may or may not freeze on startup?

I have different screen configuration.
In my home office:
I have 3 screens. My laptop screen and 2 other screens on the right. I only use the two other screens there - my laptop screen is normally off.

In the office:
I have 2 screens. My laptop screen and 1 other screen on the left. I use both screens there.

Hopefully this helps to find the problem.

Can you please elaborate a bit more on "...the problem can also be reproduced if I make an other screen to the main screen." ?

I'm trying to fill in the blanks, please correct me if I get it wrong. The laptop is the same. Perhaps you plug your laptop to a docking station at home, and when you are in the office, you plug it to a docking station in the office. In the office case your laptop screen is the main screen - monitor #1 and the other screen is monitor #2. But that changes, when you are in your home office.

When and where can you reproduce the issue? When the main monitor changes from external to laptop, or the other way? Are you able to reproduce it on demand, by simply switching the monitors and restarting SSMS? SQL Assistant "remembers" the screens for its dialogs, if you move a dialog to another screen, it attempts to show it on the same screen next time you open it. So if the monitors switch and one of them isn't used, or blank, maybe, just maybe the modal Restore Tabs dialog on startup appears on the wrong screen, which you can't see, and it blocks SSMS from loading. You can try disabling the Document Manager feature to test my theory.
