Here is the screenshot after removing pulsechain and optimism from imported chains list. Sync worked and no problem since i dont have any activity on pulsechain or optimism.

Above was created by Jack who I contacted for support. Its not correct though. Some of the transactions do show up but not all of them and actually the error message is this:

"API Error: You are reaching the maximum number of requests for this API. To avoid disruptions, please consider slowing down your requests. If you need a higher limit, consider requesting a personalized API key by visiting: https://link.avascan.info/api-key-request."

Also; The first blast wallet I added synced without problems. The latter 3 wallets did not sync. I did not spam the sync and I waited a week before I tried to sync them again and the problem persists.

EDIT: after some research the problem was only occurring when i added BLAST+"all other suggested chains" with including "pulsechain" where i dont have any activity. The link on error message might suggest that it is AVAX chain but i didnt have it listed in import optionts... It does not have any activity. For some reason the sync error is shown on the "BLAST" wallet. After I removed the "Pulsechain and optimism" and imported only blast/base/polygon wallet it worked correctly. Photos for reference.
