It's your call as to what's too hard or not, but given that you've run the two most helpful diagnostic commands and PD18 still crashed, it's very likely that PD365 will experience the same issues. That's why I recommended the above two options.
Creating a new user profile is straightforward and won't do any harm. You can also simply delete it if it doesn't change anything. If PD18/365 runs better when you're logged in to that account, you can merge your old files and settings into the new account. There are many online articles showing how to do that.
In the worst case, doing a reset will let you keep all your personal documents and files, but yes, it will require you to re-install all your apps. The good news is that while it can be time consuming, you will end up with a very solid installation where you aren't likely to have any technical issues like these for quite a while.
Either way, whenever and however you get a smoother running system, I
strongly encourage you to make regular system backups so you'll be able to simply restore your system to an earlier point in time (before the problems started) and you won't need to reinstall all your programs again.
There are free and paid apps that do this, and I hope you'll take my advice seriously. I've been working with Windows since v2.0.3 back in 1988, and I learned the hard way how having a recent full system backup can save you from uncountable hours of work and endless frustration.
