Not able to restore database - error: could not decompress data: Allocation error : not enough memory

Our database consists of 408032 blobs (pg_largeobject).
Backup was made using zstd and it weights 70GB.
While restoring the used memory increases constantly (from 5 MB to 5GB - i have got 8GB RAM, after reaching 5GB it uses 5GB for some time, maybe swaping) and then crashes with the error.
During this period it has restored about 48000 blobs.

pg_restore: error: could not decompress data: Allocation error : not enough memory

It was checked with the original pg_restore.exe and libzstd.dll as well as with compiled by mingw both 32 and 64 bits. Several libzstd.dll was used. Without success.

Dump: pg_dump.exe --format=custom --compress=zstd:4 --file=zstd.zstd  dbname=TEST
Restore: pg_restore -d TEST zstd.zstd
