Can not type in the Custom VBA Macro Form
It seems to me that the UI, which you referred to as "custom pop-ups", is shown as modeless, that is, the code that shows the UI is like
UserForm.show 1
or
UserForm Show vbModeless
When VBA 's UI (UserForm) is shown as modeless in AutoCAD, it behaves exactly as you described: it cannot hold onto the focus and user cannot interact with the UI, UNLESS an special UI control AcFocusCtrl is added to the UserForm.
Since you said this just happened recently (meaning it worked OK before), it suggests that the UI indeed had the acFocusCtrl applied to, but for some reason(s) it stopped working. Therefore, it is difficult to tell what caused it: did you install AutoCAD update, or did Windows got updated?...
You probably need to open the VB project (*.dvb file) in AutoCAD's VBA Editor to examine whether the UI has the AcFocusCtrl applied correctly (maybe it is lost for some unknown reason). When you see the UI/UserForm in VBA's editor, you should see the AcFocusCtrl on the UI, as the picture below shows:
If you do not see it, then it was lost. You would either add it back, or change the way how the UI is shown (i.e. showing the UI as modal/dialog), if applicable.
The error indicates that the the dll has a certificate issue or is not properly registered. First try this:
Open file explorer and navigate to the path below. Then right click on the dll and choose Properties. Make sure the file is unblocked. If it's not, there will be a button in the lower right to Unblock.
Open cmd.exe as an administrator. Then run the following command:
regsvr32 "C:\Program Files\Common Files\Autodesk\Shared\AcFocusCtrl.dll"

Right click on the Toolbox in the VBA editor when editing the form. Select >Additional Controls. click on the acFocusCtrl control and note the path in the bottom of the form.
Try running "rgsvr" instead of regsvr32.

Normally, no one needs to "register" acFocusCtrl separately: it installed with AutoCAD. If in doubt, you can scan Windows registry with Registry Editor. You should be able to find a key in the HKEY_CLASSES_ROOT\CLSID for this class item:
HKEY_CLASSES_ROOT\CLSID\{B5B91160-9818-4E96-BD97-B981A7AF8E06}
If you do not find it, something is wrong with your AutoCAD installation. But it is there, then things could be worse.
You want to try to reinstall AutoCAD. If you have multiple AutoCAD version installed, try VBA Editor in each of them to see whether the acFocusCtrl is not available in all ACAD versions or only in one version. At the worst scenario, you may have to uninstall all AutoCAD versions and then reinstall.
"Worse" means that it appears the AcFocusCtl component is indeed in the Window registry (COM component must be "registered" to be useful), yet, your VBA IDE does not see it. Just to be sure when you do this:
1. Go into AutoCAD VBA IDS (enter command "VBAIDE" in AutoCAD). As matter of fact, you can go to any other VBA IDE, say Excel, Word...;
2. Add a UserForm, so that the toolbox would show up;
3. Right-click the bottom of the toolbox and select "Additional Control..." context menu;
4. You should see a dialog box pops up to show all available COM UserControls available in this computer. If you do not see AcFocusCtl (yet it is registered in the registry), that is what I mean "WORSE".
It may be that the wrong version of the dll is registered. The file name should just be acFocusCtrl.dll, not *.16.dll. Did you have an older version of acad installed at one time? You might try going to Control Panel>Programs and Features and click on acad. Then choose Repair/Reinstall. Try the Repair option before reinstalling. If you need to reinstall, be sure to do a clean uninstall.

Backtracking, are you sure you installed the vba enabler for 2020 and not some other version?
You said you were too busy to upgrade. If you are going to reinstall, why not install the latest version, for which you are sure that you can get the correct vba enabler?

This might work (It might not as well) Copy the AcFocusCtrl16.dll file from one of the working PCs and overwrite the file on your machine. First check the date / time stamp on it and yours. Are they different? If they aren't you might have a corrupted file.

@staffordm Again, you could have upgraded by now and that would have most likely solved the problem.
