Error message when updating Snap Store on Ubuntu Software

[mahesh]

I've just recently installed ubuntu 22.04 LTS on my old laptop (Acer Aspire V3-111P-C6LQ; Intel Celeron N2930; 4GB DDR3: 500GB HDD). I'm a complete beginner when it comes to computing.

Upon updating the software, I received the following error message:

Unable to update "Snap Store":
(null): cannot refresh "snap-store": snap "snap-store" has
running apps (ubuntu-software), pids: 1968
Can anyone help me what does this mean and how can I resolve it? Thank you in advance.
