I tested LRC with LR6 already on MAC, but now LR6 doesn't work anymore

Lightroom Version
Operating System
  1. macOS 11 Big Sur
I own LR6 on MAC and I downloaded the trial version of LRC to understand what advantages it has.
After a few days I tried to open LR6 again but it doesn't open anymore.
I tried starting from an old backup catalog, I deleted the preferences, but nothing, it doesn't open anymore.
The image of the program being loaded appears for a moment and then disappears immediately.
Thanks for your help.

I fear you may have put an end to your use of Lr6.
From forums I have read I believe that having run a trial of LrC (by using the CC Desktop App) your Lr6 will become CC v2015.n.n, and will now require a subscription to the Photography Plan.
Do NOT un-install Lightroom. You will NOT be able to re-install Lr6! (The 32bit installer will not work in Big Sur 64bit)
Read this article which may get you reverted to Lr6-
