Is there a list somewhere of cleaning/antivirus apps to be aware of?
Usual suspects for weird problems are all add-on anti-malware, all add-on anti-virus, all add-on cleaners, all add-on VPN apps, as well as content filters in browser extensions, and content filters in firewalls.
All add-on anti-malware apps and all add-on cleaners and all add-on VPN client apps (add-on VPN apps other than those intended for connecting into the internal network of an affiliated organization) are potential suspects here, and all can do things which can stomp on normal operations. Remove them all, per the vendors’ instructions, restart, and try again. (Various of these add-ons can only be removed with vendor-provided removal tools, too.)
Try rebooting your router, as those too can get tangled.
if you want us to look at the system configuration, download and run EtreCheck, and share the report to the clipboard. Then open a new reply here, and press the button that looks like a printed page to get an Additional Text dialog box big enough for the report, and where you can paste the hardware and software configuration report into your reply here.
