Retropie not booting after trying to change resolution

[MargoProxy]

hello everyone, new to the forum

earlier today i connected my raspberry pi 4 to my 4k tv (worked on every other tv before) anyways i saw that it booted to 4k and i decided to change it to 1080p due to the size of the text being too small. i went to the retropie config and tried changing it but everytime i clicked on the change resolution option it booted me back to the advanced option menu. next thing i know its black screened and wont boot anymore once i turn it on. wont power anything connected to it and i cant use putty on my pc to use ssh. i tried my other sd card with raspbian os on it and it boots just fine just not retropie.

any help will be greatly appreciated and sorry for the bad English it is not my native language

@MargoProxy can you show your /boot/config.txt? you can access it via plugging the SD card in another computer.

wont power anything connected to it

this is a worry, though. it sounds like the SD card might be corrupt.

sorry for the late reply. heres the config https://pastebin.com/qwz2anK1
i tried just deleting everything on the card and restoring a backup to see if its a corrupted sd card like you mentioned but i came across another error altogether when i booted it up “Error parsing XML file /home/pi.emulationstation/gamelists/gbc/gamelist.xml No document found“ not sure if it has to do with the problem before or not

@MargoProxy said in Retropie not booting after trying to change resolution:

“Error parsing XML file /home/pi.emulationstation/gamelists/gbc/gamelist.xml No document found“ not sure if it has to do with the problem before or not

That's usually a sign that the gamelist.xml file is corrupt or not in the correct format. You can try deleting/renaming that file and then re-start:

rm /home/pi.emulationstation/gamelists/gbc/gamelist.xml
