Force Quit Applications

Hi everyone,

I'm fairly new to Mac's and I have a MacBook Air (macOS Big Sur, 1.3 GHz Dual Core Intel Core i5, 4 GB 1600 MHz DDR4 memory) (have had this about 3 years now and use it for basic research and social media). I have been getting a pop-up requesting to force quit applications saying there is too much memory in use. However, the only 2 apps in use are Google Chrome (with 218 mb of memory being used) and Finder (with less memory than chrome). I also get the message if I'm out of Chrome and in Safari instead.

I have looked at others' responses to other people here, and nothing I've attempted from those responses seems to fix it, or it's way over my head and I can't figure out what to do. Is this something I need to bring into an Apple store to get fixed? Or is there something I can do to fix it. It's driving me crazy!

Nothing new has been installed in a long while (over 4 months), and this is a new issue (maybe going on for 3-4 weeks).

Any help would be appreciated. Thanks!
