Board Arducam ESP32S UNO PSRAM sdmmc_send_cmd returned 0xffffffff

I am executing the sample [email protected] with the only modification of reducing the delay(5000),5 sec, to 100 (1/10 sec) and starting with number 500. The program runs fine for somewhere between 30 - 60 seconds and then an SD error occurs. Tried various cards, the latest I used is a new 32GB SanDisk extreme Plus with write speed of up to 90 MB/s. SDHC with the 3 inside U symbol.
What I need is about 20 pic/s or short one second avi’s for which I have found no samples.
Here is output I get on the serial monitor, the beginning and the end:

@JoeFritz
Hi,
I have the same problems with you. It is the official SD library’s bugs and I have copied the problem to the EP32 official support.
