Has anyone encountered sync errors caused by Steam Controller Configs (AppID: 241100)?

[C.C.]

(Use AI translation)
Since May this year, whenever I launch any game on Steam, I get the message: "Unable to sync, Steam was recently unable to sync your 「」 saves with the Steam Cloud." (The 「」 part is blank.)
(This includes games that don't support Steam Cloud.)

Following Steam Support's advice, I checked the Steam Cloud log file at (~/Steam/logs/cloud_log.txt) and found that the error is related to Steam Controller Configs (AppID: 241100), with the controller configuration sync showing an "error" due to an IO error.

The log indicates that the problematic controller configuration is from a non-Steam game I played on my Steam Deck. Even though I removed the game from the Steam Deck, the controller configuration remains in the "Steam Controller Configs (AppID: 241100)" directory on the Steam Cloud.

Now, whenever I open any game on my PC, it tries to sync all controller configurations saved in the cloud (including the removed non-Steam game), resulting in an error message.

I believe repeatedly attempting to sync the deleted game's controller configuration is a bug.

Based on my tests, simply changing the game's name alters the controller configuration, and this generates an additional controller configuration file. Eventually, this could lead to an excessive number of files, causing the Steam Cloud to run out of space.

I think this is a design flaw in the client. It would be great if related improvements could be made, or if a controller configuration manager could be provided so that players can manage these configurations themselves.

Additional Information

Regarding the IO error, I suspect that there are unsupported characters in the game name that caused the issue on the Steam Deck. Using the file manager on the Steam Deck, I can see the controller folder for the game (~\Steam\steamapps\common\Steam Controller Configs\"userID"\config\"error game"), but I can't open it, while other games don't have this problem.

Furthermore, in the "Steam Controller Configs (AppID: 241100)" directory on the Steam Cloud, the name of the problematic game also contains garbled characters like "��".
(The game name appeared normal while playing, but after being saved to the cloud by Steam, it started showing garbled characters like "��".)

===============================================================
從今年五月開始，我的STEAM開啟任何遊戲都會顯示"Unable to sync, Steam was recently unable to sync your 「」 saves with the Steam Cloud."
(「」內是空白的)
(這包括不支援STEAM雲端的遊戲)

後來聽從STEAM客服的建議查詢了Steam雲端的log檔案.(~/Steam/loges/cloud_log.txt)
發現錯誤是Steam Controller Configs (AppID: 241100)，控制配置同步出現"error"，理由是IO錯誤

log中說明錯誤的控制器配置來自我在STEAM DECK上遊玩的非STEAM遊戲
儘管我已經將出錯誤的遊戲從STEAM DECK上移除，但控制器配置依舊被保留在STEAM雲端的"Steam Controller Configs (AppID: 241100)"目錄下

現在在我的PC電腦上開啟任意遊戲時，他就會嘗試同步所有保存在雲端中的控制器設定(包括已經移除的非STEAM遊戲)，並跳出錯誤訊息

我認為一直嘗試同步已經刪除的遊戲控制器配置是一個錯誤的BUG

經過測試，只要改變遊戲名稱改變控制器配置，他就會又多出一個控制器配置檔案，最後可能會產生數量眾多的檔案導致STEAM 雲端空間不足

我認為這是客戶端的設計缺陷，可不可以進行相關的改善，或提供控制器配置的管理器，讓玩家自己進行管理

額外資訊
有關於IO錯誤的部分
我認為在STEAM DECK上出問題的遊戲名稱中存在不支援的字元，因為我使用STEAM DECK內的文件管理器可以看到該遊戲的控制器資料夾(~\Steam\steamapps\common\Steam Controller Configs\"userID"\config\"erroe game")，但點擊後卻無法讀取，其他的遊戲都沒有問題

並且在STEAM雲端中"Steam Controller Configs (AppID: 241100)"目錄下，錯誤遊戲的名稱也包含"��"亂碼字元
(遊戲名稱在遊玩時是正常的，被STEAM儲存到雲端後才除現"��"亂碼)

Here's a clearer and more organized summary of the issue, as it's quite complex and can be hard to read. Below are what I believe to be the problems and their causes:

Issue and Causes:

1.
I added a non-Steam game to my Steam Deck.

2.
I created a controller configuration for this game.

3.
Steam uploaded the controller configuration to the cloud, but there was an issue with the upload, resulting in corrupted data with garbled characters in the cloud files.

4.
When I open any game on my PC, the Steam client attempts to sync all controller configurations from the cloud.

5.
Due to the corrupted cloud files with garbled characters, an IO error occurs, causing the Steam client on my PC to display a cloud sync failure error message.

6.
I tried deleting the non-Steam game from the Steam Deck, but the problematic controller configuration remains in the cloud.

7.
I contacted customer support to request the deletion of the corrupted controller configuration from the cloud, but they stated that deleting cloud files is beyond their scope of support.

I've tried numerous other methods, including reinstalling Steam, but none of them have been effective in resolving the issue.
