Literally. I open up my terminal and try to cd Desktop only to be told that no such file exists. I thought for sure everyone this was happening to was just not reading something correctly and were foolish. Nope! It literally began deleting my files.
Edit 2: Even once it's done and you have them locally and not "on demand", the Desktop is in
~/OneDrive/Desktopinstead of~/Desktop. See this helpful comment.
It looks like there might be a way to sort of disable Files on Demand but it looks like it won't let me do it until it's done uploading? I'll post updates.
Not to be dramatic, but I'm really going through it. My mouse logitech mouse is suddenly chattering really bad and double clicking everything. Also while Steam refuses to let me disable auto updates for all games in any sort of easy way. And DDG seems intent on only showing me results related to launching games without updating (as opposed to merely disabling auto updates until I launch). The chatter fixer I found for my mouse does not work and the other requires some logitech program to even try to use. (The repo doesn't mention the name.) This is awful. When it rains it pours, I guess. Literally can't even high light this text to wrap it in a spoiler. This is fucking stupid.
Context: My parents have a family plan for Microsoft 365 they added me too and it has 1 TB of storage I can use. I wouldn't have turned it on otherwise.
Edit: My desktop background has literally vanished and turned solid black.
DO NOT ENABLE ONE DRIVE.
For your mouse double click issue, I have a g600 and ran into the same thing. It's due to a teeny tiny copper plate in the switch degrading over time. I'm not confident in my soldering skills to swap out the whole switches, but I was able to buy some new switches for like $5, pop open the little plastic switch box, carefully pull out the little copper plate with tweezers, pop open the switch on my mouse, and carefully replace the little copper plate with the new one. Worked like a charm.
Are you me? I had the same Logitech mouse click issue and fixed it the same way; ordered extra switches online, opened them, and swapped only the copper plate. Mouse click works like a charm, as you said.
