4RFV Keys not Working, but work after computer restart I have an issue of the 4RFV keys no responding to key presses on my Macbook Pro. Mine is the pro right before the M1 laptop. It must be a software issue, presumably related to an OS update. Prior to Ventura I never had this issue. It happens when I close my laptop and then reopen it later (something I regularly do as a college student between classes). However, it is not hardware related as whenI restart and/or shutdown my laptop it fixes the issues until another incident of closing my laptop. That being said it doesn't happen all of the time, but enough to be quite annoying. I don't want to simply go back to older software, but would rather the issue be figured out. Wondering if it is the browser I use: Opera GX. It also may be time to take it into the apple store, but unfortunately I require my laptop for school use. Anyways, any suggestion is taken. I don't want to revert to Monteray or an older version as that is not a permanent solution. Thanks, Grayson
