Hi glandry5577.
From your description this sounds more likely a hardware fault with the Tablet, however, which connection method are you using to connect to your Mac, which Mac model and which macOS?
If using Bluetooth to connect the tablet to the Mac, and your OS is macOS 12.x Monterey, then there are many reports across the support forum, with many different Mac models, that Bluetooth is not stable in Monterey 12.x - 12.2 and some third-party Bluetooth devices are sporadically disconnecting.
If using Bluetooth with the tablet try swapping to the supplied USB cable instead and test to see if that maintains a connection.
(Hint: When using a Bluetooth connected tablet be sure not to place your mobile phone close by the tablet, the regular “heartbeat” signal that your mobile phone emits to tell the phone network it is still alive can interrupt the Bluetooth link between tablet and Mac, a couple of feet (~600m) distance between tablet and mobile phone should be the closest the two are allowed to be in order that the Bluetooth link is not compromised)
If using USB already make sure the angled USB plug that connects to the side of the tablet has not worked loose, if this occurs during use then the Wacom driver will “lock-up” and require a Mac re-boot to restore.
I find the support advice given you by Wacom support a little odd.
Why would the touch function work one day and not the next using the latest Wacom driver and be restored only by rolling back to the previous driver? That makes no sense, unless the tablet driver is not saving its current settings when the Mac is shut down at the end of the day?
If not already tried, and the above is of no relevance, please repeat the suggested steps I made to Peter to carry out a clean install of the Wacom software, including removing the library files, and re-install the latest Wacom driver, 6.3.45-2 and not 6.3.44-2, which predates macOS Monterey.
For your convenience, here are those steps again:
Disconnect the tablet.
Drag the Wacom folder out of the Applications directory and into the Bin, empty the bin.
In finder, navigate to: <Your Mac's name> MacintoshHD > Library > PrivilegedHelperTools, and delete the files: com.wacom.datastoremanager, com.wacom.iostoremanger and com.wacomupdatehelper, empty the bin.
Back in the library scroll down further and look for a folder called "Tablet", if it exists and contains a single Wacom file delete that folder too, it did exist on my iMac Pro before I installed the latest driver package but is not there after, I suspect this was an old folder left behind from a much earlier version of the Wacom driver software.
Reboot the Mac with the tablet still disconnected.
Run the Wacom installer package 6.3.45-2 and reboot the Mac again.
Launch the Wacom Desktop Centre software, on my machine it started up this time without the spinning beach ball.
Plugin or power-on the Intuos tablet, after a few moments the tablet should be detected and allow you to setup your tablet prefs.
If these suggested steps do not resolve the problem click the “Get Support” button at the very top-right of this web page to log the problem directly with Apple techs and also make sure that Wacom support are updated that their suggestion to roll back the driver has introduced a different problem, otherwise these issues are never resolved.
HTH.
Will.
