Perhaps to arrange for the MacBook to visit and spend time with
an actual in-person inspection, diagnostic, and other testings to
see what's behind this malfunction may be best.
• Mac Repair - Official Apple Support
https://support.apple.com/mac/repair/service
The Mac goes to tech support, and you wait at a distance.
Or you may drop product off, after online details are given.
• Apple - Find Locations (sales, service, support, AASP, other)
https://locate.apple.com/
If there are Apple store or AASP service support locations,
the same kinda thing. An in-store Genius by appointment
may lead to several days or week-long service waits.
• Get Support - Apple
https://getsupport.apple.com/
Since I've never done any of those, a long story remains unsaid;
your options online are entry points, and may vary according to
the location you enter into the official Apple pages you visit.
• Genius Bar Reservation and Apple Support Options - Apple
https://www.apple.com/retail/geniusbar/
(software + hardware -or- unknown: troubleshoot-to-resolve)
[An older non-AppleCare service may primarily access AASP &
that could mean use of 'repair depot' service; remote repairs
may utilize parcel service; or internal/external tech support.]
• Apple Repair and Repair Status Check - Official Apple Support
https://support.apple.com/repair
To find 'other countries' Apple Locations; may enable the seeker
to contact the 'local/regional/country' to perhaps find an AASP.
• Apple - Find Locations - Location Selector : (sales, service, support; AASP, etc)
https://locate.apple.com/findlocations
Good luck & happy trails!
