Cannot modify or delete file: xattr: [Errno 13] Permission denied - macos

Question

I have tried multiple times to remove metadata and ACLs on a file (prompt-info.js below) so that I can modify or delete it. I have tried the answers in this question and this question (reproduced below), but nothing is working. I am running MacOS 12.1, and I do understand that ACLs have changed in recent versions of macOS. Nonetheless:
I had initially tried manually granting the file all permissions, and get this:
% ls -lah
total 136
drwxr-xr-x# 15 adamg staff 480B Jan 26 15:14 .
drwxr-xr-x# 16 adamg staff 512B Jan 20 11:39 ..
-rw-------# 1 adamg staff 2.9K Jan 18 12:34 App.css
-rw-------# 1 adamg staff 15K Jan 20 12:09 App.js
-rw------- 1 adamg staff 5.5K Jan 25 16:53 prompt-info-Adam’s MacBook Pro (2).js
-rwxrwxrwx# 1 adamg staff 5.4K Jan 20 11:47 prompt-info.js
In my terminal (iTerm2 running zsh) the filename prompt-info.js is also in red. I don't know if that helps at all.
When I try to view the metadata I get this:
% xattr -l prompt-info.js
xattr: [Errno 13] Permission denied: 'prompt-info.js'
When I try to modify the metadata I receive the same error:
% xattr -c prompt-info.js
xattr: [Errno 13] Permission denied: 'prompt-info.js'
When I try to remove the ACLs using chmod -N prompt-info.js it doesn't return an error, but then ls -lah still shows the exact same thing.
I also tried the command below, from the parent directory. It doesn't return an error, but I still receive the error about permission denied when I try xattr... afterwards:
(base) 14:24 Experiments/dialogue-keystrokes
chmod +a 'adamg allow read,write,delete,add_file,add_subdirectory,file_inherit,directory_inherit' src
Per #Gordan's comment below, when I run ls -le0#, it returns:
-rwxrwxrwx# 1 adamg staff - 5560 Jan 31 14:12 prompt-info.js
com.apple.LaunchServices.OpenWith 118
com.apple.fileutil.PlaceholderData 384
com.apple.lastuseddate#PS 16
com.apple.metadata:com_apple_backup_excludeItem 61
com.microsoft.OneDrive.RecallOnOpen 0
The full location of the directory is:
/Users/adamg/OneDrive - Northwestern University/Northwestern/Dissertation/Experiments/dialogue-keystrokes/src
Is there something I'm missing? I cannot resolve this issue.
