"The data was not successfully sent" error - MapInstall

I installed "Garmin City Navigator Europe NTU 2022.10", I try to upload map to nüvi140T but MapInstall gives me: "The data was not successfully sent".

I tried in MTP and in Mass Storage mode also, same error message.

I deleted OS manually from its internal memory and reinstalled it with WebUpdater, same error message.
I tried to install map on a memory card by copying first from internal memory the GarminDevice.xml file on memory card's Garmin folder, same error message.

Ps. I unlocked map with "UnLock MapSource" if its counting anything.
Before with any devices and maps I didn't had this error.

Why not just download a small unlocked regional map to prove your device is NOT the problem.

If you are selecting ALL of Europe 5.15 GB it will exceed the 4GB img limit.

I tried to copy unlocked IMG map file in device internal memory Garmin folder, but it doesn't show the map in device menu myMaps section

Tried with another unit, nüni 465, same "The data was not successfully sent" error.

I tried also with other year map version same error. Tis is driving me crazy... I updated many units before without any issue with same hardware

Did you rename the map from D2968360A.img to gmapsupp.img

I tried on another unit. I copied the UK map file and even without renaming the file, just copying it in internal emmory, it works. But with MapInstall it gives me the same error. I tried already 4 Garmin units already, same error. I tried with different MapInstall versions from different maps 2017, 2019, 2020, 2021, same error. This was working just fine before.
A taught, maybe this should be the issue: It gaved me update offer at first start of MapInstall. We should update to the latest version or not?

I tried the same MapInstall and map package on a freshly installed other OS and it works.

Strange: with MapSource I can send maps into device, only MapInstall can't on same laptop... I tried to uninstall, clean registry, reinstalled, same issue I give up.... I WON'T reinstall Windows for this...

Very annoying issue. I caught it on Windows and macOs. I haven't found a solution yet.
