I recently installed polytoria, and every time I enter a game, the screen goes black, and the game crashes, can anyone help me with this?

What pc do you have

It would help if you could specify what PC you have, like redlava said.
The Discord server could probably help better though.

Video card : Nvidia Quadro Fx 1800

Nvidia Quadro Fx 1800???? can that even run paint?

yeah......

when I move the game window, it doesn't get the black screen and the game crashes, but when I release the window, the black screen and crash happens, the game actually runs on my pc, I think it's a fullscreen problem.

Redownload it

Built on the 65 nm process, and based on the G94 graphics processor, in its G94 GL-U variant, the card supports DirectX 11.1. Even though it supports DirectX 11, the feature level is only 10_0, which can be problematic with many DirectX 11 & DirectX 12 titles. The G94 graphics processor is an average sized chip with a die area of 240 mm² and 505 million transistors. It features 64 shading units, 32 texture mapping units, and 12 ROPs.

Being a single-slot card, the NVIDIA Quadro FX 1800 does not require any additional power connector, its power draw is rated at 59 W maximum. Display outputs include: 1x DVI, 2x DisplayPort. Quadro FX 1800 is connected to the rest of the system using a PCI-Express 2.0 x16 interface. The card measures 198 mm in length, 111 mm in width, and features a single-slot cooling solution. Its price at launch was 489 US Dollars.

I already solved the problem, decreasing the game window, when the game window decreases, I saw that the game did not crash, I tried somehow to decrease and increase the game screen without trying to crack it, I managed to enter the settings, I configured the game's graphics, the problem that was happening was the resolution of the game that was crashing the game, the problem was solved

keep crashing lol
