Installation certificate error when running Tizen Web Application on Galaxy Watch

PROBLEM:
Error when running a Tizen Web Application on my Galaxy Watch
- error code -12: the application installation on the device has failed due to a signature error
OR
- error code -32: non trusted certificate is used. register valid certificate

This problem started after Author Certificate expired after 1 year.
Creation of a new Certificate Profile, resulting in a new Author Certificate(expires 2027/01/01) + Distributor Certificate(expires 2022/10/27), results in above mentioned problem!!
Over the past year, I have been using Tizen Studio intensively without any problems for developing Tizen Web Application for my Galaxy Watch

ENVIRONMENT:
Tizen Studio 4.1 running on Windows10 with AMD processor (configuration not changed over the past months)
Galaxy Watch Active (SM-R500) running Tizen 5.5 (configuration not changed over the past months)

PROBLEM STILL REMAINS AFTER REMOVAL / (RE-)INSTALL OF "Tizen Studo 4.1.1

error message: :Non trusted certificate is used. Register valid certificate:<-32> 
end process (fail)
processing result : Check certificate error [-12] failed

ANALYSIS
Hoping to resolve this CRITICAL error, I have removed & re-installed Tizen Studio 4.1.1.
- Using Package Manager I installed the wearable SDKs version 4.0 and 5.5
- Using the Certificate Manager I create a new Certificate Profile, resulting in new and up-to-date Author Certificate and Distributor Certificate

For testing create a new project using the "Basic Watch" sample, and tried to run it as a Web Application on my Galaxy Watch Active, resulting in the above mentioned error message. Conclusion: re-installling Tizen Studio did not change the results

HELP
Can someone please advise how to get around this problem, as this is a real showstopper!!!

Thanks in advance for your help!

SOLUTION
Creating a new Samsung Certificate solved the problem.
For this, the Samsung Certificate Extension needs to be installed through the Package Manager
see https://developer.samsung.com/galaxy-watch-tizen/getting-certificates/install.html

ANALYSIS
When generating my first certificate last year (running Tizen Studio 3.6 or 3.7), I was automatically offered the option for either a Tizen Certificate or a Samsung Certificate; I choose the Samsung Certificate.
Beginning of this year I upgated Tizen Studio to 4.1. When last years' certificate expired last week, I ran the Certificate Manager to create a new certificate. The Certificate Manager now only offers the Tizen Certificate option; I assumed this was correct and part of the upgrade. It turns out, the Samsung Certificate is still required, but in order to generate a new Samsung Certificate, the Samsung Certificate Extension needs to be installed first through the Package Manager (see https://developer.samsung.com/galaxy-watch-tizen/getting-certificates/install.html) Appearantly this extension got lost during the 3.7 -> 4.1 upgrade.
