Recently I decided to install Ubuntu Budgie 20.04 LTS after running Zorin OS (based on Ubuntu 18.04). Zorin was installed on a separate root partition, and I had another partition for /home. Naturally, I installed Budgie over / and mounted the other partition as /home.
The main reason I decided to install Budgie is that I had a particular program (AnyLogic), built in Java, that gave me some weird freezing issues even for seemingly easy operations (i.e. putting a simple plot object from the palette to the canvas, or opening example projects). The idea was to try and refresh the system and thus see if that was the culprit behind the weird issues, as I might have introduced some issues inside my Zorin OS system by installing or configuring some things. My intuition turned out correct, since I installed a fresh Zorin OS on another computer (that also gave me issues with AnyLogic before the fresh install) and then tried Anylogic--which worked just fine, with no issues.
Everything went smoothly after Budgie install, and plenty of configuration was kept--which really was great, as I only had to install many programs and they continued working as if no new system was installed.
However, this also had the bad consequence that AnyLogic still kept its freezing and other problems. My guess is that there were some configuration files or something else kept in /home that remained, and now present problems with Budgie (as / was formatted during install but /home was kept and simply mounted as home).
I also tried to delete AnyLogic's .AnyLogicPLE folder, but to no avail--AnyLogic creates a new such folder, but the problem persists. I also tried deleting other such hidden (sub)folders in /home that mentioned anylogic in any way, but it didn't help.
Now my question is, how can I go about really refreshing the system? I am ready to even reinstall everything if needed be because I really need this program to be functional. But I'd rather not do that and go through the whole setup again.
Can I, instead, delete all such hidden folders in /home and expect no big issues i.e. when programs run they'd create them again? Or how can I determine which exact such folders are accessed by AnyLogic so that I can try removing them in particular?
What would you guys suggest in this situation?
Sorry for the long letter, but I thought details would be needed here. I am a novice at Linux, so please bear with me.

Well, I 'solved' the problem by wiping everything and installing anew.
I still don't have an idea what was behind the exact problem, which is too bad since if it happens again in the future I'll have to delete everything again. But at least it is a solution of a kind.
Thanks to @Nmath and @guiverc for the suggestions.
