It's literally telling you what is happening:
Error: NoModificationAllowedError: Failed to execute 'createWritable' on 'FileSystemFileHandle': Cannot write to a read-only file.

Let's look at the error code piecemeal:
Cannot write to a read-only file.
Extremely straightforward statement, the file was read-only and it tried to do something other than read.

Then we've got this portion:
Failed to execute 'createWritable' on 'FileSystemFileHandle'
That's literally just saying that in the File System File Handle portion it failed to perform the Create Writable action, meaning there is no Writable File System File Handle portion for it to write to, hence the subsequent error mentioning that it failed to write to the read-only (non-writable) space.

Lastly, we've got this first portion, the identification label of the error:
Error: NoModificationAllowedError
It's literally just saying Error: No Modification Allowed (which is extremely straightforward).

So, in summary: the problem is that you are encountering a situation somewhere that involves attempting to access protected memory that cannot be changed from read-only to writable memory; you mentioned that this happened when you were attempting to import a file, so either your Browser has a protected memory sector getting accessed (possibly because you are importing some massive files that are megabytes or even gigabytes in size), or the Browser is attempting to access something that it doesn't have permission to access, which is common among Android Phones, as most Apps are not capable of accessing the System Files where sensitive App Data gets stored (they can access their own cache, but not the cache of other Apps).

Conclusion: try changing your Working Directory to something other than your Minecraft Directory, I would suggest a dedicated folder in your Downloads folder.
