What applications are you trying to Force Quit and why are you trying to Force Quit them? Some applications may need to be running all the time and will automatically restart (anti-virus apps, cleaning apps, third party security apps). If you mean a standard stand alone app like a browser, then that is something different. We need more details on what is happening as it should be extremely rare for anyone needing to Force Quit an app.
To look for possible software issues run EtreCheck and give it "Full Disk Access" so that the report will include more details which may provide more clues. Post the report here using the "Additional Text" icon which looks like a piece of paper so the forum contributors can examine it looking for possible problems.
