It persists with one particular file, but not the others?  Or it persists if
you open any of them?

So is the copy in the same new directory?

So you have, in that directory, two files with the exact same content, and the
file with the original name, matching the runningxx_yyyyy_zzzzzzzzzzzzzz.pcapng
pattern, has a long delay, but the identical copy, with the name 1.pcapng,
doesn't?

So files that have names that match the pattern
runningxx_yyyyy_zzzzzzzzzzzzzz.pcapng have a delay, but other files don't?

And changing the "r" in "running" to "R" gets rid of the delay?

Does this happen if you open the file by double-clicking on it, or does it only
happen when opening through the File -> Open dialog or the recently used menu?

What type of file system is on that disk - FAT of some flavor, NTFS, ReFS, or
something else?  (I'm assuming this is a local disk rather than a volume from a
server; if it's from a server, what protocol is being used - SMB, SMB2, or
something else - and what OS is the server running?)
