Thanks for the example. I can confirm those unwanted updates when
fontspec includes the euenc definitions (lm).

Afaics this is not a luaotfload error.

It is under investigation:

I can’t test with windows but it would appear this is permissions
related. Run mkluatexfondb -h to see where the database is
located. You need write permissions in that directory.

File permissions. If the database is being rebuilt over and over
again, this might be a clue that it cannot be saved to disk. The
message indicating this would be:

  luaotfload | Font names database not found, generating new one.

If it is only updated, then it’s a problem with the lookup. In
this case, the message is the one you gave in your first post:

  luaotfload | Updating the font names database:

If you are feeling adventurous, you can locate the file
“luaotfload.lua” from your distribution. Make a backup and
then comment out the line:

  fonts.define.resolvers.file = fonts.define.resolvers.name

and see if it helps.
