SupportAssist 4.0.3 Won't Get Past Start-up Splash Screen

Inspiron 5570 w/WIN 10 Home (Ver. 22H2)

Greetings!

I've reviewed numerous searches looking for an answer and am hard pressed to believe others are not experiencing the same issue, but I cannot find.

SupportAssist 3.12 worked great on this machine!  So I allowed the upgrade but ever since Dell pushed SupportAssist Ver. 4.0.3 onto this machine months ago, it has not worked.  All it does is claim that it's opening, but only spins and spins and spins for hours (2.5 hours longest attempt thus far.)  This (attached photo) is all I see, but my Windows notification bubble keeps telling me that I need to run SupportAssist.  So when I do, this is all that happens.

I'm far from a PC 'Expert' but I'm *very* comfortable working with PCs/Laptops and am well above a novice.  All "Dell Services" are running, I've turned off SuperAntiSpyware and I've tried the suggestions to delete the App, deleted entries in the Registry and reinstall, but nothing has worked.  I won't download any unknown software that someone might suggest that is 'guaranteed' to fix this issue.  Dell knows this is an issue and I would appreciate them recommending the fix.  This version is working just fine on my WIN11 machine, so please give me Ver. 3.12 back for this machine or tell me how to make 4.0.3 work here.

Thank you for your time!
