Problem running a script Python-Script in PyCharm Pro on Pinebook Pro

Hello

I have been using PyCharm Community Edition for a while on 3 different machines. 

1. A Intel-based Laptop with Windows 10
2. A Raspberry Pi 4 (8GB RAM) with Raspberry Pi OS 64bit
3. A Pinebook Pro with Ubuntu Linux

It worked on all 3, with the only issue on PB Pro, that there I couldn't open the settings panel. But as I just use it for some code review and little coding, I don't need the same configuration as on the other machines.

A couple of days ago I updated all 3 installations to Professional Edition. No changes in Performance on the Win-Laptop and the RasPi. On PB Pro still the issue with the Settings, but I still don't care. Just now, when I try to run a script, I get following error:

"While loading class net.seesharpsoft.intellij.plugins.csv.inspection.CsvValidationInspection: net/seesharpsoft/intellij/plugins/csv/inspection/CsvValidationInspection has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0 [Plugin: net.seesharpsoft.intellij.plugins.csv"

I remember on the CE I once got a small popup on the bottom right to update the CSV Plugin and there i got in to a small window with plugins only (so not as part of the settings), where I could update it.

Is this plugin essential? How can I disable it without getting into the settings? I did not find it in the plugins directory of the pycharm installation.

Hope, anyone can help me out ;)

Best regards
Yann
