outlook cannot double-click to open a message

We're having the same issue on about 10% of our workstations. Double-clicking a message or a contact does not open in a new window. The users are also reporting that double-clicking a word in Outlook to highlight it also stops working. Uninstalling webview2 causes the issue to go away...until it reinstalls itself. I've discovered that if you change Outlook to online only access (no cache or ost file) it works fine also (not a permanent solution). Microsoft has been helpful in trying to solve the issue. Most recently, they instructed me to patch Outlook to Build 16501.20210, but after a few hours the problem reappeared. It only affects Outlook. Double-clicking on anything outside of Outlook continues to work fine. As a work-around the users are highlighting the message or contact in the left column then hitting "Enter", and that opens both in a new window just fine. BTW, I've already tried all the usual; create a new profile, rebuild the cache file, etc. Also, this happens on various versions of Office - 2016, 2019, 2021 and 365
