This wee beastie I'm more sure of though, even if I couldn't get great pictures as it scuttled across the floor in the gloom.

It's very likely a (wounded) female triangle crab spider (Ebrechtella triscuspidata; Drieck-Krabbenspinne or Blattkrabbenspinne in 🇩🇪).

Crab spiders are deadly ambush hunters & I always enjoy / am horrified by them in the garden 😬✌️
