Same issue for me here.
I have a Nord Ce 5G and it happens to me constantly.
Funny thing my father has the same phone and it never seems to happen to him.
It suggests one of two things:
Either it is bad quality control/low quality parts which means some phones have this problem and others don't.
OR
it really is a problem with the proximity sensor and/or the software for it that only affects people who don't stuck their phone to the head as firmly as other does.I owned a 6T prior to this phone and never had a problem of this kind, so it's not that I'm on the extreme side of "holding the phone losely" either.
I have a bad feeling that it is the former since OP developers have acknowledged this problem for a long time now (last year), but no fix has been made to this date.

This is what you get when you buy something that seems too good to be true for the price.
I regret buying it now, even though it is (mostly) very good in every other aspect (for the price)
EDIT : I found this recalibration app that claims to fix it:

Trying it out now as I speak (literally!!).
I notice that the sensor is located at the very, very top. Maybe it's got something to do with me formerly using a phone that was "less tall" than the current phone and that I was a "holding the phone lower down close to the head" user.
It may have been "close enough" on the older "not so tall/heigh" phone for the proximity sensor to work as it should , but maybe isn't now?
The ratio for the screens have gone very wide/tall the last couple of years. It used to be 16:9 but no it is above 2:1 (19:9 or something)...
