Windows 11 folder keeps reverting back to read only

There are many possible causes for a read-only condition and, therefore, many possible solutions. Various causes and solutions have been mentioned here (and in other threads about read-only issues) by myself and others. Here is a summary of possible causes and solutions:

1. Windows Defender Controlled Folder Access (CFA), aka ransomware protection, can prevent a legitimate app from being able to make changes within folders protected by CFA. If that feature is enabled, disable it and see if that fixes the issue.
2. Third party AV software, with possibly overzealous protection settings (e.g. something similar to Windows Defender CFA), could be causing the read-only condition. Test with the third-party AV software disabled or removed.
3. OneDrive synchronization can lock out files and cause a read-only condition. Try disabling OneDrive and/or test with a new local account instead of a Microsoft account (since OneDrive will not be active by default for a local account) and see if that helps.
4. Other cloud storage software, such as Google Drive, can lead to read-only conditions (as you mentioned). Disable or remove the cloud storage software to see if that's the cause.
5. Incorrectly set, or corrupted, NTFS permissions can cause a read-only situation. Try a different folder and/or reset the owner and/or permissions of the folder in question.
6. If some process (or some person) has set all files within the problem folder to read-only (highly unlikely) then use the control, in folder properties, labelled "Read-only (only applies to files in folder)" to set all files within the folder to be not read-only and test again. Note that this control has nothing to do with whether a folder itself is read-only.
7. If the read-only condition is specific to Microsoft Office, then see this article: https://support.microsoft.com/en-us/office/why-did-my-file-open-read-only-3ab4b792-da50-4b38-8628-14c64e1f1d15
8. If the read-only condition is specific to a network share at work, then speak to your system administrator / IT department. If it's a home network share issue, then post a question providing the details, as there will likely be a lot of back and forth trial and error testing to isolate the issue.

If none of the above helps, then please provide the details of the read-only problem you're having. With specific details there's a greater chance of getting a recommendation that helps.

If you have Google Drive, turn it off. It causes read-only problems when trying to edit/delete files.

This had me stuck for a while, and ChatGPT will take you down the same CMD rabbit hole.

You are a one note pony with no solution. Professional debunker of ideas

This all just confirms my point, users can't be expected to know how to, it'ds asn error that MS should have corrected yeasrs ago, so I assume MS doesn't know whast causes it, Windows having got so complex that no one can understand it.

If your point is that there is an issue (or multiple issues) that affects some users that sometimes prevents a folder from being deleted, then, sure, I agree. If your point is that this has something to do with the item labelled "Read-only (Only applies to files in folder)" then that still remains incorrect.

There are many possible reasons a problem like this can occur in a complex multitasking OS. Some of the issues just require better reporting (e.g. the OS should tell us exactly what other process is using something without requiring additional tools) but some issues may be indeed be a bug. That's why we have to go back and forth with many questions to try to narrow down the cause (and ideally be able to replicate the issue) so that something useful can be reported to Microsoft.

This all just confirms my point, users can't be expected to know how to, it'ds asn error that MS should have corrected yeasrs ago, so I assume MS doesn't know whast causes it, Windows having got so complex that no one can understand it. I'm not wasting any more time on this crapware. MS sucks worse than Gates.
