Low Memory notice on 24" iMac M1

Two things I see that are wrong with your system.

1. First is there is no evidence that you backup the computer. If this is correct this is a 100% guarantee you will lose some data. If my assumption is correct then please buy an External Hard Disk such as a OWC Mercury Elite Pro and begin using Time Machine ( Back up your Mac with Time Machine ) ASAP to protect your data.
2. Next is the report is indicating you may have downloaded some malware. Please download the free version of Malwarebytes and run it and see if it finds anything.

Other than those 2 things the computer is fine.

You have what are likely self-inflicted wounds—malware—that are crashing:

You can use the path name for each offender to find and manually remove them.

You can also use the only tool most graybeards here consider safe: MalwareBytes. It is the work of a respected contributor here. The free version allows manual scans; the full version stops you from getting more garbage like that in real time. If you are prone to visit unscrupulous download hosting sites, you need the full version to save you from yourself! 😉

That stuff is going to mask other issues, so it has to go first.

Too often that message about low memory confusingly refers to storage space. How much Free Space is available on your drive?

Have you installed any third-party anti-virus software or so-called "Cleaning" apps? These have caused many spurious system messages.

It may be something running in the background.
