Stuck on longer imports

So I’m having this issue with my imports. What happens is that when the source folders are too many, the quiet import hangs from time to time. This also happens in the manual importing. I have been experiencing this issue for a while now, but since sometimes the import would randomly work I never really looked into it and would just restart the import when it fails.

I’m running beets in a docker container. The container is running on docker for windows desktop.
So here is my config file:

plugins: fetchart embedart convert scrub replaygain lastgenre chroma web mbsync ftintitle duplicates lastgenre lyrics
directory: /music
library: /config/musiclibrary.blb
art_filename: albumart
threaded: yes
original_date: yes
per_disc_numbering: no

convert:
    auto: yes
    ffmpeg: /usr/bin/ffmpeg
    opts: -ab 320k -ac 2 -ar 48000
    max_bitrate: 320
    threads: 2

paths:
    default: $albumartist/$album%aunique{}/$track - $title
    singleton: Non-Album/$artist - $title
    comp: Compilations/$album%aunique{}/$track - $title
    albumtype_soundtrack: Soundtracks/$album/$track $title

import:
    write: yes
    copy: no
    move: yes
    resume: ask
    quiet_fallback: skip
    timid: no
    log: /config/beet.log

lastgenre:
    auto: yes
    source: album

ftintitle:
    auto: yes
    format: feat. {0}
embedart:
    auto: yes

fetchart:
    auto: yes

replaygain:
    auto: no

scrub:
    auto: yes

replace:
    '^\.': _
    '[\x00-\x1f]': _
    '[<>:"\?\*\|]': _
    '[\xE8-\xEB]': e
    '[\xEC-\xEF]': i
    '[\xE2-\xE6]': a
    '[\xF2-\xF6]': o
    '[\xF8]': o
    '\.$': _
    '\s+$': ''

web:
    host: 0.0.0.0
    port: 8337

And here is the error i’m getting. Mind you, this is not on a specific file as far as i can tell, since it happens sometimes 1min into the import sometimes 30mins into the import.

Thanks for the quick reply Adrian. So since this seems to be a known bug, I want to do my part in helping to solve it or test a patch discussed in the bug.
Since the patch is merged with the master branch, I will update my container and see how it behaves.
