Jim, please stop. Airdrop breaks for some of us. Most of us (including me) have no vpn. There are many well-documented problems with 26.2.
Best,

Anyone having issues should run the third party app EtreCheck as suggested by @Mac Jim ID earlier in this thread and post the complete report here so we can examine it for possible clues. It is best if each person starts a new thread along with including the EtreCheck report so each person's issue can be give the full attention it deserves.

While everyone posting here may have issues with AirDrop in Tahoe, each computer may have a different cause for the problem. Many times when upgrading to a new OS or even installing a minor OS update patch, can cause compatibility issues between macOS and the existing third party software. It is vital that all third party installed software is updated to their most recent version and is confirmed to be fully compatible with the major & minor OS version of macOS being used. Sometimes it can take third party developers time to update their apps to work even with a minor OS update patch.
The most troublesome third party software is anti-virus software, cleaning/optimizer apps, and third party security software (including VPN software) since they are made to interfere with the normal operation of macOS at a very low level where they can cause the most mischief. Just disabling these types of apps may not always be enough, and some of these apps may have made permanent modifications to some critical macOS settings which may not have any easy way of knowing until something breaks.
Since none of these types of apps are needed on a Mac and they tend to cause more problems than they solve, I highly recommend uninstalling those types of apps by following their developer's instructions. An EtreCheck report can confirm whether those types of apps have been completely removed....many times critical bits may be left behind & need to be manually removed.
Of course, there may be some missed macOS/iOS configuration option or a .plist preference file on one or more of your devices that is actually corrupt. Plus the devices must be using the same AppleID and must be on the same network & discoverable by each other and each device may need to be on the most recent patch level for their OS. There are so many little bits that can go unnoticed even with just a clean install of macOS & iOS. Over the years I have had multiple occasions where AirDrop failed where sometimes just rebooting one or all devices solved the problem, or toggling AirDrop off/on fixed things.
Of course the ultimate test would be to perform a clean install of macOS by performing an "Erase All Content & Settings" to completely remove all your stuff & modifications & customizations. You will be presented with Setup Assistant like when you first booted the Mac from the factory. Just create a new user account.....do not restore or migrate anything from a backup. You need to test the Mac in a factory clean configuration with just your AppleID enabled so you can test the AirDrop feature. If AirDrop works under these conditions, then macOS Tahoe is not the problem. Keep in mind you need to make sure you have a good backup before trying this option so you minimize the chances of data loss.
People could also install & boot macOS from an external USB3 SSD to test a clean installation of macOS, just remember do not migrate or restore anything or you will likely just bring the problem back to this clean install. Installing & booting from an external USB3 SSD allows you to test a clean install without having to worry about a lengthy restoration of data to the internal SSD. Once done testing with the external macOS boot drive, you can erase the external SSD & use it for other purposes again.

Keep in mind it takes two devices for AirDrop to be successful. The problem could be with either device, or possibly both. Or perhaps, the problem is with the local network. Perhaps try AirDrop while using those devices on a different network. It takes a lot of work before it is safe to say Tahoe may be the actual cause of the problem.
I know everyone is frustrated and we do understand the frustration.
