Don't get me wrong. I love Linux and FOSS.
I have been using and installing distros on my own since I was 12.
Now that I'm working in tech-related positions, after the Reddit migration happened, etc. I recovered my interest in all the Linux environment.
I use Ubuntu as my main operating system in my Desktop, but I always end up feeling very limited. There's always software I can't use properly (and not just Windows stuff), some stuff badly configured with weird error messages... last time I was not able to even use the apt command. Sometimes I lack time and energy for troubleshooting and sometimes I just fail at it.
I usually end up in need of redoing a fresh install until it breaks up again. Maybe Linux is not good for beginners working full time? Maybe we should do something like that Cisco course that teaches you the basic commands?
In my experience, users get frustrated with Linux because they think they know a lot about computers, but in reality just know a lot about Windows. These people are unwilling to learn new workflows and OS concepts, so they get frustrated and give up. Of course, this isn't to say Linux can't be genuinely frustrating, because it 100% can be, but I think Linux and Windows are equally frustrating if you know them both well.
It's hard to say why your experience was frustrating without many more details.
Yes and no. There are the type of people who will go 'Aaarghh! I can't open my Microsoft Edge through Microsoft Cortana to use Microsoft Bing! Linux sucks!!!1!!', but there are also things in Linux that are frustrating.
The biggest annoyance to me is how small the border around windows is. On Windows, I can grab anywhere around the edge of a window and resize it, including in both directions from the corners. In Linux, I need an electron microscope to find the edges, and the hand of god to find a corner.
If I want to paste something in Windows, it's ctrl v. If I want to paste in Linux, it's ctrl v. Unless it's the terminal, which is shift, ctrl v. Or edge cases where it's shift and insert.
They don't tend to be major problems, but they break your workflow, and that makes them feel a lot worse.

This is a problem with the DE that you use and not linux in general. Gnome and KDE for example don't have this issue. I'm guessing you're using xfce?, since I had the same issue with it.
I agree with you that Linux can be frustrating, I said this in my above comment. I just don't think Linux is inherently more frustrating than Windows. I use Linux on my personal devices and servers, as well as servers at work. I also use Windows on my work laptop. I find using Windows to be a much more frustrating experience, but I know that is partially because I use Linux more often.
If you want to move windows in GNOME/KDE, you can hold the windows key + left click anywhere on the window to move it. You can do something similar for resizing with a right click instead.
ctrl+c and Ctrl+v do not work in windows CMD/powershell windows either.
