Guys. Another issue not VBA-specific but it's important. I have an excel file and it's worked just fine. Without any huge changes, currently if I do something i.e change a sheet , jst try copy a cell my application is just freeze and in task manager the CPU show me a high % of usage. GPU-0 3 D- just will be visible and the power usage change from low to very high. I run the file without releasing VBA, but the result is the same. What it is? Excel 365. (Yesterday i did a reinstalling process.) You can see a short movie with explanation related to this issue. Attached to this message.
