I can share how I solved the problem in my case.
Seems like I had MySQL Server 5.7 installed. It did not appear on the Add or Remove Programs list on Windows, so I did not know about it. I noted this after watching the XAMPP magazine.
Immediately after starting XAMPP, he showed in the log that there was a conflict in mySQL, and indicated the folder in which my MySQL Server 5.7 was installed. I manually deleted mySQL 5.7 from Program Files (x86) and the ProgramData folder, restarted it, and then XAMPP mySQL started normally.
I was only trying to stop the MySQL service, but for me this did not work. Only manually deleting all mySQL 5.7 folders seemed to help.
