Access Violation When Opening Project Options - delphi

I am using RADStudio 10 Seattle Update 1 on Windows 10 x64. I am getting an Access Violation intermittently when opening the Project Options (by right-clicking on the project, then selecting Options). I have Googled for a solution several times but have found none.
I have tried:
Disabling DEP
Restarting the IDE
this resolves the immediate error, and after it starts back up I can access the Project Options again, at least until the next time it happens.
Recreating the project.dproj by renaming and double-clicking the project.dpr to recreate
Uninstalling all third party components
Uninstalling the IDE completely, restarting the computer, and re-installing the IDE
None of these solutions seem to help. This is not happening on any specific project. It has happened to every single project I have worked on (since XE6) at least once. The problem is shared by my coworkers.
It took an hour to be able to finally get this screen shot after I started writing this post. Nothing unusual happened. I was looking through the suggested articles to make sure I hadn't overlooked something, and when I went back to the IDE and tried to go into the Project Options it happened. I must have tried 20 times over the past hour to make it happen.
Even though this is just a nusance and I can work around it, if there is a permanent solution I would love to fix this for good.
EDIT
Just noticed the "Details>>".

Access violation Fmx280.bpl

Just recently installed Rad Studio 11.2/Delphi, at first all went just fine.
But now i have error "access violation at address in module fmx280.bpl" on any action with firemonkey elements.
Creating new project, adding camera component or any other connected with FM (no any code), trying to delete it (or close form), boom! error. Tried to delete Rad Studio, clean folders, etc.

Import type library for Active DS in Delphi 2011

I'm attempting to add some Active Directory related functionality to my Delphi application. My development machine is an Azure Windows virtual machine.
When I go to Import Component | Import Type Library I do not see Active DS as a registered Type Library. If I click "Add" and navigate to C:\Windows\System32 the TLB file is there but if I try to import it I get the error "Error accessing the OLE registry" and the following impenetrable detail.
How can I register this type library and import it so that I can call active directory related Windows APIs?

Found the answer:
Delphi is unable to Add a registration for ActiveDS. However, you can do this manually from the command prompt with tregsvr -t -c activeds.tlb. Once that's the done, the library appears in the list of registered type libraries in Delphi and can be imported.

"Property Images does not exist"

I get the "Property Images does not exist" for an old project that I opened today with Delphi Tokyo 10.2 Trial.
How to (re)produce it:
Select multiple controls on a form (at design time). At least one of the controls needs to have an 'Images' property. For example, I select with Shift+Click a TLabel and a Tbutton.
For the button I see its 'Images' property listed in Object Inspector. And it seems to work ok: I can assign a list of images to it.
So, what is the actual problem? Why do I see this error (ONLY when I select multiple controls)?

How to restore object repository after adding a new project type when getting "Invalid image size" error?

I was playing around with adding a new project type to the object repository. I've added an icon and a description, but nothing else and now I can no longer do a File|New|Other, which really makes working with Delphi difficult.
I can get to the Customize menu (File|New|Customize) and I can see what I "added" and the icon is there with its description:
But when I try to go to File|New|Other, I get the Invalid image size error:
and I can't seem to figure out how to undo what I did. Clicking on Details button yields the following:

Two ways roll this back:
1) delete the RADStudioRepository.xml file that resides in \AppData\Roaming\Embarcadero\BDS\12.0. Delphi recreates a default file when restarted
2) edit the RADStudioRepository.xml file to remove the offending entries.

What can cause a "Catastrophic failure" error in Delphi IDE

I am dead serious about this: I got a "Catastrophic failure" while editing my code in IDE!
What can cause this? It looks like the error started here: Forms.TApplication.ActivateHint
Well, the IDE is working after restart. But I wanted to post it also because it is a bit funny (actually you MUST admit it is quite funny).

It's an IDE bug. There are plenty of them. There's not very much that you can do about it. And it could be a problem either with Delphi or with a plugin.
You are running XE, and there will be no more updates to XE. You could try Andy Hausladen's IDE FixPack. That might help. You could perhaps see if you can isolate a reproduction of the fault, and then find a way to work around it.
